Stem Cell Therapy: How Your Body’s Repair Cells Can Heal Injury and Degeneration
Stem cells are undifferentiated cells capable of becoming specialized tissue. Regenerative medicine harnesses them to repair damaged joints, tendons, and organs — with results that can rival or exceed surgery.

What Is Stem Cell Therapy?

Stem cell therapy is a regenerative treatment that uses either your body’s own stem cells or carefully selected donor-derived stem cells to repair damaged or degenerating tissue. Stem cells are unique because they can both self-renew and differentiate into specialized cell types — bone, cartilage, muscle, nerve tissue, and more.

During treatment, stem cells are either harvested from your adipose tissue (fat) or bone marrow, concentrated, and injected directly into the damaged area. Alternatively, umbilical cord-derived or placental-derived stem cells may be used, depending on your condition and your provider’s protocol.

The injected cells then promote repair by reducing inflammation, stimulating the production of new tissue, and creating a healing microenvironment that supports your body’s natural regenerative capacity. Stem cell therapy has shown promise across orthopedics, neurology, cardiology, and autoimmune conditions — making it one of the most versatile regenerative treatments available.

How Does Stem Cell Therapy Work?

Stem cells work through multiple mechanisms simultaneously:

  • Direct tissue replacement — Stem cells differentiate into functional cells that replace damaged tissue
  • Paracrine signaling — Cells release healing molecules (cytokines and growth factors) that reduce inflammation and trigger repair
  • Immunomodulation — Stem cells can calm overactive immune responses, beneficial in autoimmune and inflammatory conditions
  • Angiogenesis — New blood vessel formation improves oxygen and nutrient delivery to healing tissue
  • Anti-apoptotic effects — Stem cells prevent damaged cells from undergoing programmed cell death, preserving viable tissue
 

The result is tissue regeneration at a deeper biological level than surface-level growth factor therapies alone can achieve.

Frequently Asked Questions

Where do the stem cells come from?

Stem cells can be sourced from your own body (autologous — typically from fat or bone marrow), from donor tissue (allogeneic — umbilical cord, placenta, or amniotic tissue), or cultured in a lab. Your provider will recommend the best source based on your condition and desired outcome.

If harvesting your own cells, the full procedure typically takes 2–3 hours. If using off-the-shelf stem cells, the injection can be done in 30–60 minutes. Most patients go home the same day.

Stem cell therapy stimulates a gradual biological healing process. Most patients notice improvement between 4 and 12 weeks, with continued progress over 6 months as new tissue develops and inflammation subsides.

The FDA does not “approve” stem cell therapies the way it approves drugs. However, stem cell products are regulated as human cells and tissues. Many providers use FDA-registered and cGMP-compliant stem cell products manufactured under strict standards.

Costs typically range from $3,000–$8,000+ per treatment depending on the cell source, number of injections, and treatment area. Most insurance does not cover stem cell therapy at this time, though some plans may cover a portion for specific conditions.
