Regenerative medicine is a field of clinical practice and research focused on restoring or replacing the function of tissues that have been damaged by injury, disease, or aging — using the body's own biological processes of repair, signaling, and growth. Instead of simply managing symptoms, regenerative approaches aim to support or stimulate healing at the tissue level. That distinction is what places regenerative medicine at the heart of modern anti-aging and functional medicine.
For patients, the appeal is intuitive: a therapy that helps the body heal itself. For clinicians, regenerative medicine spans a spectrum — from well-established, in-office procedures such as platelet-rich plasma to investigational cell and exosome products that carry significant regulatory scrutiny. Understanding where each therapy sits on that spectrum is essential to practicing responsibly, and it is the focus of this overview.
What is regenerative medicine?
At its core, regenerative medicine seeks to do something most conventional treatments do not: change the trajectory of a tissue by promoting repair rather than only relieving symptoms. A symptomatic approach to a painful joint, for example, might focus on reducing inflammation or pain. A regenerative approach asks whether the body's own healing response can be supported or amplified at the site of damage.
The field draws on several scientific threads — the body's platelets and the growth factors they release, the signaling roles of peptides and proteins, and, in research settings, the regenerative potential of various cell types. In everyday practice, the term is used broadly. It can describe a straightforward office procedure using a patient's own blood, or it can refer to far more complex, investigational biologics. Because of that range, "regenerative medicine" should always be understood in terms of the specific therapy in question, not as a single, uniform treatment.
Core regenerative medicine therapies
The approaches below are the ones clinicians and patients ask about most. Descriptions here are general and educational — not treatment recommendations — and evidence and regulatory status differ for each.
Platelet-rich plasma (PRP)
PRP is prepared by concentrating the platelets from a small sample of a patient's own blood and reintroducing that concentrate at a site of interest. Because platelets carry growth factors involved in healing, PRP is among the most widely used regenerative procedures in clinical practice, particularly in musculoskeletal and aesthetic settings.
Peptide therapy
Peptides are short chains of amino acids that act as signaling molecules. Some are used in regenerative and recovery contexts to support tissue repair and other biological functions. Regulatory status varies by peptide, which is covered in depth in our companion guide on what peptide therapy is.
Exosomes
Exosomes are tiny vesicles released by cells that carry signaling cargo. They are an active area of research and marketing in regenerative medicine, but it is important to be clear: exosome products are investigational, and the FDA has not approved exosome products for these uses. Claims about them are heavily scrutinized.
Growth factors
Growth factors are proteins that signal cells to grow, divide, and repair. They are central to why approaches like PRP are studied, and they appear in various regenerative formulations. As with other categories, the specific product and its regulatory status determine how it may be used.
Prolotherapy
Prolotherapy involves injecting a solution intended to provoke a local healing response in connective tissue such as ligaments and tendons. It is an older technique within the regenerative space, used primarily for certain musculoskeletal concerns, with evidence that varies by application.
What regenerative medicine is used for
Regenerative approaches are explored across several areas. Patients should understand that the strength of evidence differs considerably by therapy and by application, and that many uses remain emerging rather than definitively established.
- Musculoskeletal & joint — one of the most common areas, where PRP and related techniques are used for tendons, ligaments, and joints.
- Aesthetic, skin & hair — PRP and other regenerative methods are used in facial rejuvenation and hair-restoration contexts.
- Sexual health — certain regenerative procedures are marketed in this area; evidence varies and claims should be measured.
- Recovery & tissue repair — supporting healing after injury or in connective-tissue concerns.
A responsible clinician matches the therapy and the claim to the evidence behind it, rather than applying a single regenerative label uniformly across very different conditions.
Evidence and the regulatory landscape
This is the most important section for any provider considering regenerative medicine. The honest picture is one of contrast: some therapies are well-integrated into practice, while others are investigational and tightly regulated.
PRP, which uses a patient's own blood, is widely used in clinical settings. By contrast, many cell-based and exosome therapies are investigational and fall under FDA regulation. The FDA actively restricts unapproved stem cell and exosome products and has taken action against clinics making unsupported claims. Marketing language that promises cures or definitive regeneration from such products often outpaces the evidence and the law.
Who can offer regenerative medicine
Many regenerative procedures — PRP among them — can be offered by licensed physicians, nurse practitioners, physician assistants, and nurses, within their scope of practice and state regulations, after appropriate clinical training. Scope, supervision requirements, and what may be legally offered vary by state and by therapy. Investigational biologics carry additional regulatory obligations. Knowing the boundaries of one's scope and the regulatory status of each therapy is a baseline requirement, not an optional refinement.
Patients evaluating regenerative care should ask providers direct questions: which specific therapy is being used, whether it is FDA-approved or investigational, what the realistic evidence and expected outcomes are, and how the provider was trained to perform it. A confident, transparent answer to those questions is itself a meaningful trust signal — and a clinician who has invested in structured education is far better positioned to give one.
Get trained in regenerative & anti-aging medicine
The Academy of Anti-Aging & Functional Medicine at Empire Medical Training offers CME-accredited courses across regenerative therapies, peptides, hormone optimization, and aesthetics — taught by board-certified physicians, with an emphasis on evidence and the regulatory landscape. Empire provides CME certificates of completion, not board certification.

Adding regenerative procedures to a practice is less about memorizing a list of therapies and more about clinical judgment: which approach fits which patient, what the current evidence supports, how to source and document responsibly, and where the regulatory lines sit. A strong program teaches technique alongside this reasoning. Empire's regenerative curriculum is part of the broader Academy of Anti-Aging & Functional Medicine, alongside the Peptide Therapy Master Course, IV nutrient therapy, and foundational training in anti-aging medicine. The courses are clinical education, not medical advice, and prepare providers to offer regenerative services thoughtfully and within their scope.
