What Is Regenerative Medicine Used For?

Regenerative medicine is used to try to do one of three things with damaged tissue:

• Repair it.
• Restore it.
• Replace it.

Today it falls into two very different buckets.

The first is a narrow set of FDA-approved cord-blood-derived stem cell products. They are used for certain blood cancers and immune disorders.

The second is a much larger, mostly investigational category. It includes PRP, mesenchymal stem cell injections, and exosome products. These are marketed for the following (U.S. Food and Drug Administration, 2020; Mayo Clinic, n.d.):

• Orthopedic pain.
• Sports injuries.
• Other chronic conditions.

The bucket a product falls into changes what it can legally claim to do. It also changes whether strong evidence backs it. So it's worth knowing the difference before you consider one.

What This Means

In plain terms, "regenerative medicine" is an umbrella term. It is not one specific procedure.

The FDA-approved stem cell products are blood-forming stem cells (hematopoietic progenitor cells) derived from umbilical cord blood, approved specifically for disorders that affect blood production, and, since December 2024, one mesenchymal stem cell product for steroid-refractory acute graft-versus-host disease in children (U.S. Food and Drug Administration, 2020). None is approved for orthopedic, pain, or cosmetic use.

Everything else marketed under the regenerative medicine umbrella today falls outside that list. That includes:

• PRP for joint pain.
• Mesenchymal stem cell injections for orthopedic conditions.
• Exosome products for skin or hair.
• Investigational research into neurological or cardiac disease.

Each is either being studied in clinical trials, or offered outside FDA approval as an investigational therapy.

Candidacy

Regenerative medicine is most often considered by patients with chronic joint pain, tendon or ligament injuries, or osteoarthritis. These patients have tried more conservative care without lasting relief (Goulian et al., 2025). Those usually include:

• Physical therapy.
• Anti-inflammatory medication.
• Corticosteroid injections.

It is not a fit for everyone.

Patients are typically poor candidates if they have:

• Active infections.
• Certain cancers.
• Uncontrolled autoimmune disease.
• Bleeding disorders.

Pregnant patients are generally excluded. Candidacy is not universal. A thorough medical evaluation is the right starting point before any responsible recommendation. A marketing brochure is not.

Clinical Evaluation

A reasonable clinical work-up before regenerative medicine includes:

• A detailed history of the injury or condition.
• A physical exam.
• Often imaging such as X-ray, ultrasound, or MRI, to confirm the diagnosis.

This also helps rule out conditions that regenerative injections would not help. A full-thickness tendon tear may need a different approach entirely. So may advanced bone-on-bone arthritis.

Bloodwork may be ordered to screen for:

• Infection.
• Clotting problems.
• Autoimmune markers.

A licensed provider should also review your medication list. Blood thinners and some anti-inflammatories can affect candidacy or timing.

Say a clinic offers to inject you the same day you walk in, without imaging or labs. That's worth questioning.

Available Options

Regenerative medicine sits alongside conventional care. It is not a substitute for it.

Mainstream options for chronic joint and soft-tissue pain include:

• Physical therapy.
• Oral or topical anti-inflammatory medication.
• Corticosteroid injections.
• Hyaluronic acid ("gel") injections.
• Bracing.
• Weight management.

When conservative measures fail, surgical options such as arthroscopy or joint replacement may be considered.

Within regenerative medicine itself, patients usually encounter three categories:

• PRP (concentrated platelets from your own blood).
• Mesenchymal stem cell injections (from bone marrow or adipose tissue).
• Exosome products (cell-derived signaling particles).

A good provider will walk you through where each option fits next to conventional alternatives. A good provider will not present any of them as a universal replacement for standard care.

Benefits, Limitations & Risks

Benefits

Some patients report reduced pain and better function after PRP or stem cell injections for orthopedic conditions.

Researchers are actively studying these approaches. Recent literature identifies mesenchymal stem cell therapy as showing meaningful promise. That promise is for pain reduction, in some studies (Goulian et al., 2025).

Limitations and risks

Real limitations apply:

• Response varies a lot from person to person.
• Results are not guaranteed.
• Effects, when present, may be temporary.

The evidence base is still developing. That is especially true for uses outside orthopedics, such as neurological, cardiac, or autoimmune conditions.

Risks include injection-site pain, swelling, and infection. With unapproved or poorly sourced cell products, more serious complications are possible. The FDA has received reports of the following, linked to unapproved regenerative products:

• Tumor formation.
• Infections.
• Blindness.

What the Evidence Shows

What's established

Published trials generally report that PRP and mesenchymal stem cell injections were well tolerated in study settings, when properly sourced and given. Long-term safety data are limited, and this is not a finding that any product is safe or effective for a specific use. A growing body of orthopedic literature links MSC therapy with pain reduction. That is in some patient groups (Goulian et al., 2025).

What evidence does not establish

The evidence does not yet establish:

• Long-term durability of results.
• Optimal dosing and cell counts.
• Clear superiority over conventional treatment for most conditions.

Researchers and health-economics reviewers have specifically flagged two ongoing challenges for the field. They are the lack of long-term outcomes data and the lack of pricing transparency (Qiu et al., 2022).

In plain terms: there's real research interest and some encouraging orthopedic data. But take a claim that regenerative medicine makes a condition go away. For most uses, the current evidence does not support that. And no clinic should present it that way.

Recovery / Next Steps

Recovery from a regenerative medicine injection is usually short. Most patients have mild soreness or swelling at the injection site for a few days. Most can resume light activity within 24–72 hours.

A gradual return to full activity usually follows, over one to a few weeks. The exact time depends on the joint or tissue injected and the protocol used.

Response is gradual. So a provider will commonly schedule a follow-up visit, at several weeks to a few months. That visit assesses progress before deciding whether additional injections are warranted.

Orlando Considerations

Florida law shapes how stem cell therapy can be marketed in Orlando. It also shapes how that therapy is delivered.

Under Florida Statutes § 458.3245, a physician may perform stem cell therapy that isn't FDA-approved. That is allowed only for these indications:

• Orthopedic.
• Wound care.
• Pain management.

The physician must source cells from FDA-registered and accredited facilities. The physician must also give patients a specific written notice. That notice discloses that the therapy has not been FDA-approved. A signed informed-consent form is required before the procedure (Florida Legislature, 2025).

Any Orlando clinic offering stem cell therapy should be able to show you two things. Those are the consent process and the disclosure. They should show them without hesitation. If they can't, that's a red flag.
