Regenerative medicine has become one of the most talked-about areas of modern healthcare. As more people look for alternatives or complements to traditional approaches for joint discomfort, sports injuries, hair and scalp concerns, sexual wellness, and healthy aging, three terms appear again and again: MSC stem cells, exosomes, and platelet-rich plasma (PRP).

Although all three are associated with regenerative medicine, they are not the same thing. They come from different sources, contain different biological components, and are used in different ways.

At Balanced Medical Solutions in Hayward, California, we use regenerative medicine approaches that include mesenchymal stromal/stem cells (MSCs), exosomes, and PRP, depending on the patient’s goals, medical history, treatment area, and individual circumstances.

For localized applications, our regenerative medicine protocols may include MSC stem cell injections for knees and other joints, scalp injections, and penile injections using MSCs in combination with Vitti-Pure. For intravenous applications, we use stem cell derived exosomes rather than administering MSCs intravenously.

But what exactly is the difference between these therapies? Why might someone choose MSCs instead of PRP? What are exosomes? And why does the source of MSCs matter?

Let’s take a closer look.

What Is Regenerative Medicine?

Regenerative medicine is a broad field of medicine focused on understanding and supporting the body’s natural repair and biological processes. Unlike conventional medications that are often designed primarily to manage symptoms, regenerative medicine investigates biological materials, cells, growth factors, signaling molecules, and other approaches that may influence the local tissue environment.

Three commonly discussed regenerative medicine approaches are:

• MSC stem cell therapy
• MSC stem cell derived exosome therapy
• Platelet-rich plasma (PRP) therapy

While they overlap in some of the biological pathways they may influence, they are fundamentally different therapies. One of the most important distinctions is that PRP contains components derived from your own blood. MSC therapy uses living mesenchymal stromal/stem cells. Exosome therapy uses stem cell derived extracellular vesicles and their molecular cargo rather than administering intact MSC cells. Understanding that distinction is essential when comparing regenerative medicine treatments.

What Are MSC Stem Cells?

MSC stands for mesenchymal stromal cells, often referred to as mesenchymal stem cells. MSCs are a type of multipotent stromal cell that has been extensively studied in regenerative medicine research. They can be obtained from several sources, including bone marrow, adipose tissue, umbilical cord tissue, and placental tissue.

One option is autologous MSC therapy, meaning cells are obtained from the patient’s own body. For example, a patient’s own adipose tissue or bone marrow may be collected and processed to obtain cells for a procedure. There is another approach: allogeneic MSCs, meaning the cells originate from a donor.

At Balanced Medical Solutions, we use newly donated MSCs derived from umbilical cord/Wharton’s Jelly tissue obtained through U.S.-based, FDA-regulated cord/tissue banking sources and screened donor programs, rather than harvesting MSCs from the patient’s own body. This distinction is important.

What Is Wharton’s Jelly?

Wharton’s Jelly is a gelatinous connective tissue found within the umbilical cord. It surrounds and protects the umbilical blood vessels during fetal development. Wharton’s Jelly has become an important source of MSCs for regenerative medicine research because it contains populations of mesenchymal stromal cells.

The appeal of using donated umbilical cord-derived MSCs is partly related to the fact that the cells can be obtained without harvesting tissue from the patient. Instead of undergoing a fat or bone marrow harvesting procedure, the patient can receive cells sourced from appropriately screened donated tissue.

Why does the source matter?

The source of MSCs can make a substantial difference in the characteristics of a cell-based product. Factors that may matter include:

• donor screening
• tissue source
• cell processing
• cell characterization
• manufacturing procedures
• storage and handling
• quality-control testing
• consistency of the final product

At Balanced Medical Solutions, our philosophy is to use newly donated MSCs from carefully screened donors rather than asking patients to undergo a tissue-harvesting procedure. We believe this offers several practical advantages.

First, the patient does not have to undergo a separate procedure to harvest tissue. Second, donated neonatal tissue provides access to MSC populations that have not been obtained from an older patient’s own tissues.

Donated Wharton’s Jelly provides a convenient and well-studied source of MSCs with several practical and biological characteristics that make it attractive for regenerative medicine research and clinical protocols.

Why Use Donor MSCs Instead of the Patient’s Own Cells?

Patients sometimes assume that using their own cells must automatically be better. This is not necessarily true. Autologous MSC therapy has an obvious advantage: the cells come from the patient’s own body. However, obtaining those cells generally requires a harvesting procedure.

Depending on the source, this may involve:

• adipose tissue harvesting
• bone marrow aspiration
• additional processing
• additional procedural time
• recovery from the harvesting procedure

There is also an important biological consideration. The characteristics and potency of a patient’s own cells can vary with age, health, metabolic status, and other individual factors. Donor-derived MSCs from younger tissue offer a different starting material. This is one reason umbilical cord and Wharton’s Jelly-derived MSCs have attracted significant interest in regenerative medicine research and therapies. At Balanced Medical Solutions, we use newly donated MSCs from screened donors rather than harvesting MSCs from our patients.

What Are Exosomes?

Exosomes are very different from stem cells, although they are derived from stem cells. An exosome is a type of extracellular vesicle – a tiny membrane-bound structure released by cells. Each MSC has an average of 5,000 exosomes. Exosomes contain biological molecules, including proteins, lipids, messenger RNA, microRNA, and other molecular cargo.

One of the reasons exosomes are so interesting to researchers and for therapeutic applications is that cells can use extracellular vesicles as a form of cell-to-cell communication. In simplified terms, you can think of exosomes as microscopic biological “messengers.” They don’t contain an intact stem cell. Instead, they carry molecular signals that influence how other cells respond. This distinction is extremely important:

MSC therapy involves cells. Exosome therapy involves cell-derived extracellular vesicles.

MSC Stem Cells vs. Exosomes

The easiest way to understand the difference is to think about what is actually being administered.

MSC therapy

MSC therapy involves living mesenchymal stromal cells. Researchers have studied MSCs for their ability to interact with surrounding tissues and influence the local biological environment through multiple mechanisms.

Exosome therapy

Exosome therapy involves extracellular vesicles produced by stem cells. These vesicles can carry biological signaling molecules and are being investigated and used by early adopters for their potential role in cell-to-cell communication and regenerative processes.

What Is PRP?

PRP stands for platelet-rich plasma. Unlike donor-derived MSC therapy and exosome therapy, PRP is typically autologous, meaning it comes from the patient’s own blood. To obtain it, a small amount of blood is collected and processed to concentrate platelets and plasma. Platelets are best known for their role in blood clotting, but they also contain numerous proteins and growth factors involved in tissue repair and healing processes.

During a PRP procedure, the concentrated platelet-rich portion of the blood is prepared and then injected into the treatment area. PRP has been studied extensively in areas such as sports medicine, orthopedics, tendinopathy, and musculoskeletal conditions. The evidence varies depending on the specific condition and treatment protocol, so PRP should not be thought of as a universal treatment for every injury or disease.

MSC Stem Cells vs. PRP

One of the biggest differences between MSCs and PRP is what they contain. PRP is derived from your own blood and contains concentrated platelets and plasma components. MSC therapy involves mesenchymal stromal cells derived from the patient or the Wharton’s Jelly inside donated placentas and umbilical cords.  This means the biological mechanisms being investigated are different.

PRP

• Derived from the patient’s blood
• Generally autologous
• Contains concentrated platelets and plasma
• Provides growth factors and other blood-derived components
• Commonly used in musculoskeletal and sports medicine applications

MSC therapy

• Can be autologous or allogeneic
• Contains mesenchymal stromal cells
• Can be sourced from tissues including bone marrow, adipose tissue, umbilical cord, and placenta
• Has been extensively studied in regenerative medicine research
• May be used in localized injection protocols

Neither therapy should automatically be considered “better.” The appropriate option depends on the treatment objective, anatomy, patient characteristics, and the clinician’s assessment.

MSCs, Exosomes and PRP: A Side-by-Side Comparison

What Are MSC Stem Cell Injections Used For?

The potential applications of MSC-based regenerative medicine are broad, but it is important to distinguish research interest from proven medical indications. At Balanced Medical Solutions, our localized MSC-based protocols include several areas.

Knee and Joint Injections

One of the most widely discussed applications of MSC therapy is joint-related regenerative medicine, particularly the knee. Researchers have conducted numerous clinical trials evaluating MSC-based injections for knee osteoarthritis and other joint conditions.

A 2024 systematic review and meta-analysis of 25 randomized controlled trials involving more than 1,000 participants found that advanced MSC therapy showed reductions in pain compared with viscosupplementation at 12 months. Another systematic review of randomized controlled trials published in 2025 found that many studies reported improvements with stromal cell-based injections compared with non-operative treatments. In other words, the research is promising, but it is still evolving.

At Balanced Medical Solutions, MSC joint injections are considered as part of an individualized regenerative medicine approach for appropriate patients. Thus far, the success rate in regards to noticeable improvements is approximately 90%, especially when coupled with Vitti-Pure.

Vitti-Pure + MSC Stem Cells: A Regenerative Medicine Combination

Vitti-Pure is a proprietary regenerative wellness formulation designed to complement cellular-based therapies by providing additional biological support to the treatment environment. At Balanced Medical Solutions, we combine Vitti-Pure with mesenchymal stromal/stem cells (MSCs) for select regenerative medicine applications, including our knee regenerative protocols.

While MSC stem cells can also be paired with PRP, the MSC + Vitti-Pure combination provides a more comprehensive regenerative approach than MSC’s combined with PRP. However, direct clinical studies comparing the two combinations are limited but our own case studies have shown that this combination shows much better results than MSCs with PRP.

Scalp Injections

Another application of regenerative medicine is the scalp. Hair thinning and hair loss can have many causes, including genetics, hormones, aging, nutritional issues, medications, and underlying medical conditions. Because hair follicles are biologically active structures, researchers have become interested in whether cellular and extracellular signaling may influence the scalp environment.

At Balanced Medical Solutions, we offer scalp injections using our regenerative medicine protocols. The objective is not to promise that stem cells will “cure” hair loss. Rather, the treatment is part of an emerging area of regenerative medicine research involving cellular signaling and tissue-support mechanisms. Patients should undergo an appropriate evaluation to determine the likely cause of their hair loss before deciding on any treatment.

Penile Injections and Sexual Wellness

Regenerative medicine has also attracted interest in the field of male sexual wellness. At Balanced Medical Solutions, we offer penile injections using MSCs in combination with Vitti-Pure as part of our regenerative medicine and sexual wellness protocols.

Research into regenerative approaches for erectile dysfunction (ED) is ongoing, including investigations involving stem cells, extracellular vesicles, growth factors, and other biological therapies. However, patients should understand that regenerative approaches for ED remain an evolving area of medicine and although they are showing promising results with many of our patients, results can vary.

A comprehensive sexual health evaluation remains important because ED can be associated with vascular health, hormones (low testosterone), medications, metabolic health, neurological factors, psychological factors, and other conditions.

Why Does BMS Use Stem Cell Derived Exosomes for Stem Cell IV Applications?

At Balanced Medical Solutions, we distinguish between our localized MSC applications and our intravenous MSC derived exosome applications. For IV regenerative medicine protocols, we use exosome-based therapy rather than administering MSCs intravenously.

Why Exosomes May Be Particularly Well-Suited for Systemic IV Therapy

For systemic intravenous therapy, exosomes offer several potential advantages over administering whole MSCs directly into the bloodstream. Exosomes are extremely small, cell-free extracellular vesicles that can travel through the circulation and deliver biologically active signaling molecules to distant tissues. Their nanoscale size and natural cellular-communication properties may allow them to cross biological barriers that are difficult for many therapies to reach, including the blood-brain barrier. Research has demonstrated that exosomes can cross or interact with the blood-brain barrier, creating exciting possibilities for supporting cellular communication and repair mechanisms in the brain and nervous system.

Similarly, researchers are investigating exosomes for potential applications in retinal conditions, including age-related macular degeneration, because extracellular vesicles may interact with the blood-retinal barrier and influence inflammation, cellular signaling, and tissue-protective pathways. Another important distinction is the concentration delivered: at Balanced Medical Solutions, a standard Exosome IV contains at least 1.7 trillion exosomes, providing a concentrated source of extracellular vesicles and their associated signaling cargo throughout the body.

Because exosomes are cell-free, they also avoid some of the theoretical concerns associated with introducing large numbers of living MSCs intravenously, including cellular interactions within the pulmonary microcirculation and coagulation pathways. While exosome therapy remains an emerging area of regenerative medicine and more clinical research is needed to establish its effectiveness for specific diseases, their ability to circulate systemically, communicate with distant cells, and potentially access tissues protected by biological barriers makes exosomes an especially interesting approach for whole-body regenerative and wellness applications.

Note: Patients interested in exosome IV therapy should understand that this is an emerging area of regenerative medicine, not an FDA-approved treatment for a specific disease.

What Are PRP Injections Used For?

Platelet-rich plasma (PRP) injections use a concentrated preparation of platelets derived from the patient’s own blood. Because platelets naturally contain growth factors involved in tissue repair and cellular signaling, PRP has been used in a variety of regenerative applications, including painful joints, soft-tissue injuries, hair and scalp treatments, and sexual wellness. PRP can be injected directly into areas where additional regenerative signaling is desired, making it a versatile treatment option. At Balanced Medical Solutions, however, our experience has led us to favor MSC stem cell injections combined with Vitti-Pure over PRP alone for many joint and scalp applications. We believe this combination provides a more comprehensive regenerative approach for these areas, while we use PRP almost exclusively for our specialized sexual wellness treatments, where the patient’s own platelet-rich plasma can be precisely administered to targeted tissues.

PRP for Sexual Wellness

At Balanced Medical Solutions, PRP is most commonly used as part of our Male Climax PRP Shot and Female Climax PRP Shot treatments. For men, the Male Climax PRP Shot uses PRP prepared from the patient’s own blood and injected into penile tissue. According to our patient education materials, reported benefits include supporting soft-tissue repair, stimulating the formation of new blood vessels, increasing blood circulation and sensation, and potentially helping men experiencing erectile dysfunction (ED).

For women, the Female Climax PRP Shot involves targeted PRP injections into the clitoris and G-spot. Our patient education materials describe potential benefits including enhanced orgasmic response, increased sensitivity, rejuvenation of vaginal tissues, improved natural lubrication and elasticity, reduced discomfort during intercourse, increased sexual enjoyment, and help with urinary incontinence.

Because PRP is produced from the patient’s own blood, it is a naturally derived treatment that delivers concentrated platelets and their associated growth factors directly to the treatment area. At Balanced Medical Solutions, this makes PRP particularly well suited to our targeted sexual wellness protocols, where the goal is to support circulation, tissue health, sensitivity, and sexual function. As with any regenerative treatment, individual results vary, and patients should undergo an evaluation to determine whether a Climax PRP Shot is appropriate for their specific goals.

Are Stem Cells, Exosomes, and PRP FDA Approved?

This is an important question – and one every patient should ask before receiving regenerative medicine treatment. The short answer is that “FDA-regulated,” “FDA-cleared,” and “FDA-approved for a specific medical treatment” are not the same thing. The FDA regulates products, biological materials, and medical devices used in regenerative medicine, but that does not mean that every stem cell, exosome, or PRP treatment offered by a clinic is FDA-approved for the condition being treated. At current time, the FDA only regulates the way biological materials such as stem cells and exosomes are harvested, stored, treated, and transported.

PRP is somewhat different. PRP is prepared from a patient’s own blood, and the FDA has cleared certain devices for the preparation of autologous PRP for specific labeled uses. However, an FDA-cleared PRP preparation device should not be confused with FDA approval of PRP injections for every condition or treatment protocol in which PRP may be used. The specific device clearance and its intended use matter.

Early adopters are able to access these experimental treatments at clinics like Balanced Medical Solutions with “off label” applications showing promising results in clinical trials.

What Does This Mean for Patients?

Patients should be particularly cautious of any clinic that simply states that its stem cell injections, exosome IVs, or PRP treatments are “FDA approved” without explaining exactly what has been approved and for what indication. At Balanced Medical Solutions, we believe patients deserve transparency about the source and handling of regenerative medicine products. Our MSCs and exosomes are sourced through U.S.-based, FDA-regulated cord and tissue banking sources, with donor screening and quality-control processes. We specifically use newly donated, donor-derived MSCs from umbilical cord/Wharton’s Jelly tissue rather than harvesting tissue from the patient. For our exosome therapies, we use exosome products sourced through established U.S. tissue-banking channels. This sourcing standard is an important part of our approach and is particularly relevant when patients are comparing treatment options in the United States with clinics in other countries, where regulatory requirements, oversight, and enforcement may differ.

Ultimately, FDA regulation or oversight of a source, tissue bank, processing system, or medical device should not be represented as FDA approval of the regenerative treatment itself. At Balanced Medical Solutions, we encourage patients to ask questions, understand exactly what is being administered, where it comes from, and how it is processed and handled.

 

Which Treatment Is Right for You?

There is no single regenerative medicine treatment that is right for everyone. The best approach begins with determining what problem you are trying to address. For example, if you’re experiencing knee or joint discomfort, an evaluation may determine whether PRP, an MSC-based injection, an exosome IV, conventional orthopedic treatment, physical therapy, or another option makes the most sense. In the case of hair thinning or loss or male sexual wellness support, the first step is to determine the likely cause.

At Balanced Medical Solutions, our approach is to match the regenerative medicine strategy to the patient and application and be upfront and honest if we feel there is not a good chance of success or improvement with any of these regenerative medicine approaches. Most importantly, we believe patients should have realistic expectations. Regenerative medicine is an exciting and rapidly developing field and although we have seen amazing results with many of our own patients, many applications remain under active investigation. No responsible clinic should promise that stem cells, exosomes, or PRP will cure every condition.

Frequently Asked Questions

Are MSCs the same as stem cells?

MSCs, or mesenchymal stromal cells, are commonly called mesenchymal stem cells. They are a type of multipotent stromal cell that has been extensively investigated in regenerative medicine.

Where do MSC stem cells come from?

MSCs can come from several sources, including a patient’s own bone marrow or adipose tissue, as well as donated tissues such as umbilical cord and placental tissue. At Balanced Medical Solutions, we use only new MSC stem cells from donated placentas of healthy donors and from cord banks regulated by the FDA.

What are Wharton’s Jelly stem cells?

Wharton’s Jelly is connective tissue within the umbilical cord that contains mesenchymal stromal cells. It is an important source of MSCs for regenerative medicine research.

Are Wharton’s Jelly MSCs better than your own stem cells?

Not necessarily in every clinical situation. Different MSC sources have different characteristics, and there is not sufficient evidence to universally declare one source superior for every application. At Balanced Medical Solutions, we choose donor-derived Wharton’s Jelly MSCs because they avoid harvesting tissue from the patient and provide access to brand new MSCs from donated neonatal tissue.

Are exosomes stem cells?

No. Exosomes are extracellular vesicles released by stem cells. They are not intact stem cells.

Is PRP made from my own blood?

Yes. PRP is generally prepared from a patient’s own blood and concentrates platelets and plasma components.
