How does stem cell therapy work?

P Written by: Phil Kim Medically reviewed by: Dr. Robert Aki, DPM Last medically reviewed: October 9, 2026

Stem cell therapy works by placing concentrated cells from your own body into an area that is struggling to heal, so those cells can support the tissue's natural repair response. The process involves collection, preparation, and a guided injection, all in one clinic visit.

The collection step

The cells are collected from your own body, usually from bone marrow or fat tissue. The collection site is numbed first, and the sample is small. Most patients tolerate the collection well.

Preparation in the clinic

The sample is processed in the clinic to concentrate the cells and the signaling proteins they carry. Because everything happens the same day, the prepared cells are delivered fresh rather than stored or shipped.

The guided injection

The concentrated cells are injected into the area being treated, guided by the provider's assessment of your anatomy and imaging. The goal is to place the cells where the tissue needs the most support.

What happens after

Regeneration takes time. Improvement, when it comes, typically builds over weeks to months. You leave with written recovery instructions and a follow-up plan, and your team tracks progress at follow-up visits.
