What You Need To Know About Stem Cells
You may have heard about stem cells in the news or maybe it was mentioned by a friend. After searching for more about it online, you may have come across websites or scientific journals that discussed the topic in a very complicated way.
You are not alone. While there are a lot of people who are interested in learning about stem cell-based treatments, there’s also a lot of clutter online and even misleading information about what it is and how therapies are administered. Contrary to popular belief, stem cell-based approaches are not a matter of a single injection or a single therapy session. Where they are used, this usually involves a series of applications within an individual medical plan.
So, if you are considering stem cell treatment for your condition or you simply want to learn more about it, you have come to the right place. Here, we break down all the important things you need to know about stem cells in the simplest way possible, so you can make your important decision with a clear mind.
We’ve listed down and answered all the frequently asked questions about stem cells, including:
- How to choose your stem cell clinic or product?
- What is the potential of stem cells?
- What are stem cells?
- Why are they important?
- Where do they come from?
- How does stem cell therapy work?
- How much do stem cell therapies cost?
- Which diseases are stem cell-based approaches being researched for?
Learn about all these and more in our guide to stem cells and to the conditions in which stem cell-based approaches are currently being researched.
How to Choose a Stem Cell Clinic?
How to Ensure Safety of a Treatment?
The most important point when choosing a stem cell treatment should always be your safety. Make sure that the stem cell clinic is officially controlled and works under GFP/GMP. In Germany, the regulatory presidium of the federal states and the Paul Ehrlich Institute are responsible for this. They only grant licenses if the consistent quality of the stem cells is guaranteed and the production is carried out in such a way that there are no concerns regarding patient safety. Quality control plays an important role here.
Important questions: Does the clinic in its country have a manufacturing permit or a tissue collection permit? Does an international clinic have a permit from the competent national authority? ANOVA IRM in Offenbach has corresponding permits for BMC and secretome since 2018.
Are Allogenic or Autologous Stem Cell Therapies Better?
Compare the products offered. Allogenic products from foreign donors are always associated with more risk than autologous stem cells (donor and recipient are the same person). These greater risks include transmission of pathogens (viruses, bacteria) and allergic reactions. Allogeneic products should only be used if they are immunologically safe or the matching of donor and recipient has been verified.
Important questions: Is the product autologous? If not, how is matching tested? How are the donors tested? Testing in accordance with current regulatory standards includes hepatitis B and C, HIV 1 and 2, and Treponema pallidum (syphillis). Other diseases are usually not tested. Therefore, autologous stem cells avoid this specific risk, because they cannot transmit an infectious disease from a donor. This concerns donor-transmitted infection only and does not mean that a treatment is free of other risks.
How Much Time Does Stem Cell Therapy Take? What is the Duration?
Many patients want to be treated quickly. However, care should be taken as products are only safe if patients are also tested beforehand. For this purpose, blood tests are used, which usually take 1 day. If you are not tested beforehand, you cannot be sure if previous patients have contaminated the premises with bacteria or viruses.
Question for the clinic: what donor selection tests do they do in advance?
Beware of Animal Stem Cells, Fresh Cells and Unclear Products!
Animal stem cell products can be very dangerous and should not be used. Their potential of contamination, infection and allergic reactions is generally high. Always check with the appropriate legal authority in advance. All products that are not clearly and transparently explained should be considered questionable. For all allogenic therapies, ask explicitly about the donors and donor testing, i.e. what the donors were tested for.
Why We Do Not Offer SVF - Stromal Vascular Fraction
The stromal vascular fraction (SVF) is a product we do not offer. It is obtained from adipose tissue in an isolation procedure lasting approximately 2 hours and contains only a few stem cells. Due to the manual, open isolation process, contamination may occur. Since SVF is applied immediately after isolation, sufficient quality control cannot be performed to detect the potential contamination.
BMC, by contrast, is isolated in a closed system, which reduces the opportunity for contamination during processing. MSC or MSC secretome generated from SVF cells are cultured, which allows time for in-process quality control. The secretome is frozen after production, so the end product itself can be analysed before it is released.
Contraindications
Our stem cell treatments are experimental, but we only treat patients for whom we believe the risk/benefit ratio indicates treatment based on the state of the art, i.e., medical, scientific evidence.
Please understand that we therefore do not treat patients for whom the following points apply:
- Active cancer in the last two years
- Not yet of legal age
- Existing pregnancy or lactation period
- Unable to breathe on own, ventilator
- Difficulty breathing in supine position
- Dysphagia (extreme difficulty swallowing)
- Psychiatric disorder
- Active infectious disease (Hepatitis A, B, C, HIV, Syphilis, or other)
How do Stem Cells Work? Effect Hypotheses for Stem Cell Treatments
Stem cells are said to have two basic modes of action:
- Immunomodulation (influencing the immune system, mostly inhibiting excessive immune reactions)
- The promotion of tissue regeneration
In the early years of stem cell research, it was assumed that stem cells would replace damaged tissue by "integrating" themselves into the tissue. Current research no longer supports this idea. Instead, laboratory research suggests that stem cells act as moderators and modulators. In this research model, stem cells introduced into an inflamed area are thought to influence the local immune response, for example by "communicatively convincing" the triggering immune cells to let the inflammation subside. The communication is described as taking place via messenger substances that are released by the stem cell and either bind to the outside of the immune cell and trigger signals or are taken up by the immune cell and then trigger a signal inside. The "communicators" in their totality are referred to as the secretome, which contains exosomes, microvesicles, cytokines, miRNA (micro RNA), and proteins. This proposed moderation is called immunomodulation.
The second hypothesised mode of action is the promotion of regeneration. In preclinical and laboratory research, stem cells appear to "motivate" cells in damaged tissue to divide and to support repair processes. Research also suggests that regeneration can be blocked while inflammation is present, which is why both proposed mechanisms are being investigated together. The exact way in which stem cells act is not understood. Neither stem cells nor their messengers (secretome, exosomes) are approved medicinal products; they are used in research and in individual treatment approaches, and a clinical benefit for patients has not been established.
What are Stem Cells?
A stem cell is a very special type of cell that can replicate and develop into many different cell types in the body during early life and growth.
Because of this, they become a repair mechanism of the body. By dividing without limits, they replenish all the other cells. And with each new division, it has the potential to either remain a stem cell or another type of cell with a special function.
Essentially, they can become a muscle cell, a red blood cell, or even a brain cell.
What are Embryonic Stem Cells?
This is a special type of stem cell that is pluripotent. This means that they can change into any type of cell. They are very important because if you’re sick and you need healthy cells for a certain part of your body, then they can replace the unhealthy ones.
However, there have been ethical issues about the method of getting embryonic stem cells. At ANOVA, we only use stem cells that are sourced in a regulated and ethical way (not from embryonic sources), obtained from the patient's own tissue.
What are Adult Stem Cells?
Despite their name, they can be found in the bodies of both children and adults. They have the potential to renew the entire tissue from which they come from, with just a few cells.
Why do Adults Have Stem Cells?
Their purpose is to maintain and repair the tissue where they are located. It is part of our body’s self-healing system.
Where are Adult Stem Cells Found?
They are located in many organs and tissues, including the brain, bone marrow, blood, muscle, skin, and many other areas. This is why adult stem cells are the more widely used source in stem cell research and raise fewer ethical concerns than embryonic stem cells.
Here at ANOVA, all our available stem cell treatments use mesenchymal stem cells (MSCs), which are obtained from fat tissue or from bone marrow. Using cells taken from the patient’s own body avoids the transmission of infections from a donor and reduces the risk of immune rejection. It does not mean that a treatment is free of risks or side effects.
What is the Difference Between Embryonic and Adult Stem Cells?
Embryonic and adult stem cells vary in their abilities. They also differ in number and type of cells they can become. To be more specific, adult stem cells can only transform into several types of cells but embryonic stem cells can become all cell types of the body.
Embryonic stem cells can also be grown in a laboratory, while adult stem cells come from the patient, so they may be harder to grow. However, this makes them less likely to be rejected by the patient’s immune system after the procedure. This is one of the reasons why we have chosen to use adult stem cells at ANOVA.
What are Pluripotent Stem Cells?
Pluripotent is a characteristic of a cell and not a separate cell type. This trait in cells simply means that they can self-replicate and have the ability to develop into other types of cells or tissues.
Also called the “master cells”, they're able to make cells from the different body layers so they can potentially produce cells or tissues the body needs to repair itself.
What are Hematopoietic Stem Cells?
A hematopoietic stem cell is a subtype of an adult stem cell that originates in the bone marrow. Also called the “blood stem cell”, it can differentiate into all types of blood cells, including white blood cells, red blood cells, and platelets. They are usually found in the bone marrow and in the peripheral blood.
What are Multi-Potent Stem Cells?
They have the power to renew or refresh themselves. After they divide themselves, they can develop into different types of specialized cells. As such, most adult stem cells are multi-potent stem cells.
What are Mesenchymal Stem Cells?
Mesenchymal stem cells, or MSCs, are a type of multipotent stem cell, which can differentiate into a variety of cell types, including fat cells, bone cells, muscle cells, cartilage cells, and more.
As previously mentioned, this is the type of stem cell that we use at ANOVA.
Do Plants Have Stem Cells?
Plants don’t have stem cells similar to humans. However, their cells have a kind of vitality that allows them to provide a steady supply of cells that can form differentiated tissues and organs.
The two characteristics mentioned -- the ability to create mature cell types and the ability to self-renew -- are what make them special. Because of these two qualities, they protect plants and help them withstand the harsh environment and external factors.
Plants are immobile and they can get damaged easily, so their stem cells are their way of protecting themselves.
Why are Stem Cells Important?
They have several uses, both in research and in healing:
- Research is investigating whether they can support the repair of damaged tissue. For this reason they are the subject of research and clinical studies in conditions such as:
- Spinal cord injuries
- Parkinson's disease
- ALS or amyotrophic lateral sclerosis
- Alzheimer's disease
- Heart disease
- Type 1 diabetes
- Stroke
- Burns
- Osteoarthritis
Improvements have been reported in individual cases, but the available evidence is early and limited and does not establish effectiveness. Further clinical trials are needed. Listing a condition here does not mean that a treatment for it is established, approved, or offered by ANOVA. - Researchers are also studying them to understand how diseases occur and how to best fight them. By studying how they develop into different kinds of cells, doctors can better understand how diseases start and develop.
- They can also be used to test new medicine and its safety and quality. Because they can replicate other types of cells, they can take on the properties of the types of cells a specific drug aims to target. For example, if a new medicine for heart disease is being tested, then it can be used on stem cells that mature into heart cells. Researchers will find out whether the cells were harmed during the clinical trial of the drug and whether it is safe to administer to patients.
Where do Stem Cells Come From?
Researchers have discovered several sources:
- Embryonic - They come from embryos that are three to five days old.
- Adult - They can be found in tissues such as bone marrow or fat.
- Perinatal - They are located in the amniotic fluid and blood from the umbilical cord. They also have the ability to change into specialized cells.
Who Discovered Stem Cells?
There is an ongoing debate about who discovered them. Their discovery is usually attributed to Canadian scientists Drs. James Till and Ernest McCulloch. However, they were mentioned in scientific journals before Till and McCulloch’s pioneering studies in hematopoietic stem cell research.
When Where They Discovered?
There were many studies that used the term “stem cells” before Till and McCulloch’s 1963 research. The earliest ones date back to the ‘30s and ‘40s.
For example, in a 1932 research paper on the effects of radiation on cells, American scientist Dr. Florence Sabin mentioned that one of the types of cells that can be damaged by radiation are hematopoietic stem cells.
In 1936, the same Dr. Sabin published an article about the relationship of stem cells and white blood cells.
What made Till and McCulloch’s paper different from previous works is that their research focused on hematopoietic stem cells, while others were on stem cells from hematopoietic tumors.
When did Stem Cell Research Take off?
Scientists usually work with two types of stem cells: embryonic and non-embryonic or "adult" stem cells. This started in 1981 when scientists extracted stem cells from mouse embryos. In 1988, this study helped researchers harvest them from human embryos, which are later grown in laboratories.
Roughly two decades later, scientists have reprogrammed specialized adult stem cells genetically to function like a stem cell. These are called induced pluripotent stem cells and this breakthrough paved the way to new research and treatments
How are Embryonic Stem Cells Harvested?
“Harvesting” or the act of getting them can happen in many ways. The way they are harvested affects how they are used in the research or treatment of diseases.
Before, embryonic stem cells were harvested by destroying a human embryo and this became quite controversial. In newer, more advanced techniques, this process was eliminated because it was found that they could be extracted from blastomeres, a cell formed on the outer layer of a fertilized ovum. This avoids the destruction of the embryo.
On the other hand, adult stem cells need to be harvested directly from the source where they would also be used. For example, for the treatment of blood diseases, you would need a blood stem cell. And you can extract them from the bone marrow, where blood is produced.
At ANOVA, we harvest stem cells in an ethical way and under regulated, quality-controlled conditions. For all our treatments, we use the patient’s own fat or bone marrow to extract mesenchymal stem cells for our treatments. ANOVA does not apply or employ embryonic stem cells.
How are Mesenchymal Stem Cells Harvested?
Mesenchymal stem cells can be extracted from different sources.
Stem cells from fat tissue are extracted using nutational liposuction, which allows the removal of fat without destroying your cells. At the same time, this minimally invasive procedure only requires local anesthesia and light sedation. Afterwards the fat is transferred into a sterile container for further processing in the laboratory to extract the cell fraction.
Stem cells can also be extracted from bone marrow. This can also be performed using local anesthesia. Red more about Bone Marrow Concentrate here.
What are Stem Cells Used for?
Stem cells are used for both research and therapy.
Of course, one of the most important applications is their use in stem cell-based therapies. Stem cell-based approaches are being investigated in a number of conditions. Read more about it here.
Nowadays, donated organs are used to replace ones that were malfunctioning. However, this process can take longer because of the lack of suitable donors. Regenerative medicine is researching whether stem cells could one day offer an alternative, because in the laboratory they can differentiate into specific cell types. This is a long-term research goal, not an available treatment. Unlike donor organs, stem cells are a renewable source and would not depend on donor availability.
As mentioned previously, stem cells can also be used for research purposes. Research in the field of embryonic stem cells, for example, can help us further understand what happens during human development. With the help of research, scientists can identify how stem cells become differentiated cells, which eventually form into the tissues and organs.
Research in this field highly contributes to the ongoing studies on serious medical conditions, such as cancer and birth abnormalities. This is because these diseases are caused by atypical cell division and differentiation. By understanding these conditions better, we are a step closer to finding cures and strategies for therapy.
Stem cells can also be used to test new drugs. For example, new medicines are tested on differentiated cells generated from human pluripotent stem cells.
What do Stem Cells Look Like?
Each cell type has its own size and structure appropriate for its job.
For example, brain cells communicate commands to the body so they’re shaped like webs because they need to reach out to the different types of cells surrounding them.
Even if these cells have different functions, they all consist of the same main components:
- Nucleus - Contains DNA which contains information about the body.
- Cytoplasm - Liquid surrounding the nucleus which contains the materials the cell needs to do its job.
- Cell Membrane - Surface of the cell which sends and receives signals from other cells so they can perform their tasks.

How Does Stem Cell Therapy Work?
The way the therapy works depends on the approach. There are two fundamentally different approaches to stem cell therapy.
In the first approach, stem cells are extracted from the source and re-applied to the patient where it is needed. Research is investigating whether the re-applied cells can support regeneration and tissue repair at that site.
The source can be fat tissue, bone marrow, or other tissues from the patient’s own body. The location and type of re-application depends on the condition that is being treated.
At ANOVA, we extract bone marrow and re-apply Bone Marrow Concentrate (BMC) containing MSCs to the patient. Read more about it here.
In the second approach, stem cells are also extracted from the same sources, but they are used to produce the stem cell secretome, or stem cell exosomes. In this approach, it is not the cells that are being applied, but the cell-free stem cell secretome.
The secretome is defined as the sum of all soluble molecules (e.g. growth factors and cytokines) that are being released from the cell. These molecules are mainly utilized by the cell to communicate with other cells. They can initiate different mechanism in the surrounding cells.
Why is the stem cell secretome being researched? Recent research indicates that the effects observed with stem cells in laboratory and preclinical studies may largely originate from these released molecules. Read more about the stem cell secretome and current research here.
How Much Does Stem Cell Therapy Cost?
There are many clinics in North America that advertise stem cell therapy. Some of their treatments can set you back USD 4,000 to USD 7,000.
A report by American media agency PBS also states that in some clinics, treatments for the whole body can cost USD 20,000 to USD 30,000.
In Germany, stem cell treatments can start around 5.000 Euro for single treatements up to some ten-thousand for treatment programs with repeated infusion. Examples of the diseases or conditions requiring this type of treatment include:
- Crohn’s disease
- Multiple sclerosis
- Neurodegenerative diseases, like Alzheimer’s disease and dementia
- Psoriatic or rheumatoid arthritis
Despite these costs, many people in the US or Canada still try them out because it’s comparably cheaper to treatments done in Europe. However, these clinics have been called out due to compliance and ethical issues.
Therefore, before you start any treatment, it’s worth researching the clinic. Take the advice provided by the FDA on stem cell clinics in North America to heart and make sure the clinic you choose is compliant to government regulations. Treatment in Europe may cost more, but regulatory oversight and manufacturing standards are strict. This concerns the quality and safety framework around manufacturing; it is not a statement about how effective a treatment will be.
Make sure the clinic can explain its procedures, its permits and its quality controls to you transparently.
How much do stem cell injections cost?
Prices vary depending on type of stem cell, type of tissue source, type of treatment, and country. There are clinics in the US and Canada which are reportedly pricing stem cells injections at USD 5,000 to 50.000. In Germany, stem cell treatments start at around 5.000 up to some ten-thousand Euro.
At ANOVA, we consider these injections only a part of the whole therapy program, which we plan individually and holistically for each patient. Get in touch with us so we can give you an estimate on how much a therapy at ANOVA costs.
In Which Diseases Are Stem Cell-Based Approaches Being Researched?
Stem cell treatment is not a cure-all. In a number of conditions, early and mostly small clinical studies are investigating stem cell-based approaches. The findings so far are preliminary and do not establish effectiveness. The sections below summarise where research currently stands; they are not statements about the benefit a patient can expect.
Stroke and Heart Disease
For many survivors of stroke, thrombolysis or the dissolution of the blood clot is the main option available to manage the acute event. Stem cell-based approaches are being investigated in early clinical research as a possible further option. These findings are preliminary, effectiveness has not been established, and side effects cannot be ruled out.
Parkinson’s Disease
A disease affecting millions of people around the globe, it’s unfortunate that Parkinson’s disease currently has no known cure. What many patients do is simply suppress the symptoms by undergoing hormone replacement-based therapies. Unfortunately, this does not stop neural degeneration or replace dead brain cells.
Clinical studies with mesenchymal stem cells (MSCs) so far provide early, still limited findings that require further investigation, with regard to both benefit and safety. Secretome Therapy is being examined in this research context. It is not an established alternative to approved medication and is not a substitute for it.
Erectile Dysfunction and Impotence
Men of all ages can be affected with erectile dysfunction and reduced potency, which are often linked to diabetes and high blood pressure. Established medications for these conditions mainly address the symptoms rather than the underlying cause.
Stem cell-based approaches are being explored in early research in this area; effectiveness has not been established. Any individual treatment plan requires a prior medical assessment and should also address nutrition and lifestyle.
Osteoarthritis
As the leading cause of pain and disability in the world, osteoarthritis has stopped many people across the world from living a mobile and dynamic life.
Early clinical research is investigating stem cell-based approaches in osteoarthritis. The available studies are small and preliminary; they do not show that these approaches are superior to standard medication.
Research into cell-free approaches such as Secretome Therapy is examining possible mechanisms, including the modulation of immune responses. These are research questions, not established treatment effects.
Knee Injuries
Those with knee injuries or knee degeneration may feel that they have limited therapy options. Cell-based approaches are being researched as a possible option alongside established treatments.
Initial clinical studies are investigating whether cell-based approaches can support healing in knee injuries; these findings are early and limited. Surgery may still be necessary, and the safety of combining it with cell-based approaches has not been established.
Back Pain and Spine Conditions
Back pain and spine problems are commonly treated with surgery or with pain medication. They can affect patients in all aspects of life, which is why research is also looking at approaches that address the underlying degeneration rather than the symptoms alone.
Stem cell-based approaches are being investigated in this context; effectiveness has not been proven. The approaches studied include Bone Marrow Concentrate (BMC) and Mesenchymal Stem Cells (MSC).
ALS - Amyotrophic Lateral Sclerosis
Also known as motor neuron disease or Lou Gehrig’s disease after a popular baseball player with the same condition, ALS is characterized by severe motor dysfunction because of the loss of nerve stimulation.
There are studies which suggest that stem cell therapy can be a promising new approach to protect the motor neurons of ALS patients.
RA - Rheumatoid Arthritis
Rheumatoid Arthritis (RA) is an autoimmune disease for which no cure is currently available. Stem cell-based approaches are the subject of early research, which is investigating whether they can influence inflammation, modulate immune responses and support tissue repair. These are research questions; a benefit for patients has not been established.
Related conditions discussed in this research context include psoriatic arthritis, juvenile idiopathic arthritis, vasculitis and gout.
MS - Multiple Sclerosis
Medications available for multiple sclerosis aim to slow the progression of the disease rather than to reverse it. Stem cell-based approaches are the subject of early clinical research in MS, which is investigating possible effects on inflammation and on nerve tissue. The findings so far are limited and preliminary, a benefit for patients has not been established, and these approaches are not a substitute for established MS therapy.
Anti-Aging
Anti-aging is an area of active scientific interest. Research is examining whether cell-based approaches can influence regenerative processes at the cellular level. This work is at an early stage: there is no evidence that such approaches slow, stop or reverse ageing, and no rejuvenating effect can be promised.
What are the Side Effects of Stem Cell Therapy?
Side effects can occur. Reported effects include, for example, nausea or vomiting after treatment. In addition, every procedure used to obtain cells (such as bone marrow aspiration or liposuction) and every application carries its own risks, including pain, bleeding and infection. Which risks are relevant depends on the patient’s condition, the specific procedure and the disease concerned. Because these treatments are not approved medicinal products, the full side effect profile is not established.
This is why at ANOVA, we make sure that we do a thorough examination of every patient and tailor fit our therapy to their special needs.
Is it Possible to Increase Stem Cells Naturally?
Proper nutrition and a healthy lifestyle are generally regarded as beneficial for the body’s own repair processes, although the direct effect on human stem cells has not been clearly established.
Some studies explore whether their activity can be influenced, for example this 2018 Massachusetts Institute of Technology study, which reported faster intestinal stem cell regeneration in mice after a 24-hour fast. Findings of this kind are preclinical and cannot be transferred directly to patients.
There are certainly many new discoveries in the field and here at ANOVA, we are excited about the many possibilities that this can contribute to the constant improvement of our treatments.
If you want to explore your stem cell therapy options with us, we are more than happy to answer your inquiries.
Does Medical Insurance Typically Cover the Therapy?
Treatment programs at the ANOVA Institute for Regenerative Medicine are not covered by health insurance at the moment. They are available only on a self-pay basis.
We are happy to talk to you about your payment options. Feel free to reach out to us by sending an email or calling us.
How can I Donate Stem Cells?
While there are other clinics that receive donations, here at ANOVA, we do not use them on our patients.
For our procedures, we use adult stem cells obtained from the patient’s own fat tissue or bone marrow, which avoids the immunological compatibility problems that can arise with donor material.
