Regenexx-SD Procedure: Information for Health Care Providers

Stem cells are heavily advertised all over the Internet. We recognize the need for significant basic science information on stem cell therapies so that consumers and medical professionals can make informed decisions.

What type of stem cells are these?

These are the patient’s own (autologous) bone marrow derived mesenchymal stem cells (MSC’s) and Hematopoetic Stem Cells (HSC). They are isolated in the lab from a bone marrow aspirate via a nucleated cell isolation.

How much clinical experience do you have with the use of stem cells?

We began using stem cell concentrates in 2005-2006 and then cultured stem cells in 2006 in human subjects as part of IRB approved research studies. As a result, our medical practice has as much or more experience in the use of mesenchymal stem cells for orthopedic conditions as any other site in the world. We have performed thousands of stem cell based procedures.

Is this the same as BMAC or a bone marrow concentrate prepared at the bedside in a centrifuge?

No, see this discussion.

Is this the same as Platelet Rich Plasma?

No, PRP is a concentration of blood platelets that can help stimulate repair of tissue. We do use various advanced platelet preparations to allow cells to grow in culture and help cells engraft once they are re-implanted, but these platelet preparations must be prepared in a lab facility and can’t be created using a bedside centrifuge.

What is the MSC selection procedure?

We use a proprietary lab separation method to select an enriched MSC and HSC population. These are then reinjected in the same surgical procedure.
