Stem Cell Therapy vs. PRP: What's the Difference and Which Is Right for You?

Stem Cell Therapy vs. PRP: Understanding the Difference

Both stem cell therapy and PRP (platelet-rich plasma) are categorized as regenerative medicine, and both are offered by many of the same clinics. But they work very differently, cost very different amounts, and have different levels of clinical evidence.

What Is PRP?

Platelet-rich plasma (PRP) is made from your own blood. A sample is drawn and spun in a centrifuge to concentrate the platelets, which contain growth factors that promote tissue healing.

How it works: PRP delivers a concentrated dose of growth factors to the treatment area, stimulating the body's natural healing response.

Cost: $500–$2,500 per injection

Evidence: Moderate. PRP has the strongest evidence for lateral epicondylitis (tennis elbow), mild knee osteoarthritis, and hair loss. Evidence is weaker for other conditions.

What Is Stem Cell Therapy?

Stem cell therapy uses actual stem cells — cells that can potentially develop into different tissue types — to repair or replace damaged tissue.

How it works: Stem cells are harvested (from bone marrow, fat tissue, or donor sources), processed, and injected into the target area, where they may differentiate into the needed cell type or release anti-inflammatory signals.

Cost: $3,000–$50,000 depending on the condition and cell type

Evidence: Variable. Stronger for some orthopedic conditions; more limited for neurological and systemic conditions.

Side-by-Side Comparison

| Factor | PRP | Stem Cell Therapy |

|--------|-----|-------------------|

| Source | Patient's own blood | Bone marrow, fat, or donor cells |

| Mechanism | Growth factor delivery | Cell differentiation + signaling |

| Cost | $500–$2,500 | $3,000–$50,000 |

| Evidence level | Moderate (some conditions) | Variable (experimental for most) |

| FDA status | Generally accepted | Experimental for most uses |

| Recovery time | 1-3 days | 1-7 days |

| Number of treatments | Often 1-3 | Often 1-3 |

Which Should You Choose?

Consider PRP if:

• You have mild to moderate tissue damage
• Cost is a significant factor
• You want a treatment with more established evidence
• You have tennis elbow, mild knee OA, or hair loss

Consider stem cell therapy if:

• You have more severe tissue damage
• PRP has not provided adequate relief
• You are willing to accept more uncertainty for potentially greater benefit
• Your condition is one where stem cell research is more active

Many clinics offer both, and a combination approach is common. Use the [StemConnect quiz](/quiz) to find clinics that offer both options and can advise you on the best approach for your specific condition.
