Procedures & Specialties

Regeneris Medical offers a promising new approach to preventing disease and mitigating symptoms, with potential to be more effective than the tools of 20th-century medicine. Click below to see procedures and physicians in each division of our network.


What diseases and problems can be treated?

This will depend on the type of degenerative condition you have. A specialist will evaluate you and discuss your candidacy for stem cell therapy. If, after you’ve been recommended for treatment, you have a complete understanding of the potential risks and benefits, and have decided that you would like to explore this avenue of treatment, you can be considered for treatment. Of course, even though it’s a minimally invasive procedure, you will still need to be medically cleared for the procedure.

Is our procedure FDA approved?

Regeneris surgical procedures fall under the category of physician’s practice of medicine, wherein the physician and patient are free to consider their chosen course of treatment. The FDA does have guidelines about treatment and manipulation of a patient’s own tissues. At Regeneris Medical we meet these guidelines by providing same day treatment with the patient’s own cells that undergo minimal manipulation and are inserted during the same visit.

Does Regeneris Medical use embryonic stem cells?

No. Only adult mesenchymal stem cells are used. These cells are capable of forming bone, cartilage, fat, muscle, ligaments, blood vessels, and certain organs. Embryonic stem cells are associated with ethical considerations and limitations.

Recent advances in stem cell science have made it possible to obtain high numbers of quality multi-potent (able to form numerous other tissues) cells from a person’s own liposuction fat. Regeneris Medical uses state-of-the-art technology to process this fat to yield approximately five hundred thousand to one million stem cells per cc of fat, and therefore, it is possible to obtain as many as 10 to 40 million cells from a single treatment. These adipose (fat) -derived stem cells can form many different types of cells, including bone, cartilage, tendon (connective tissue), muscle, blood vessels, nerve tissue and others.

Are any biological agents or growth factors added to the stem cells?

Our adipose derived stem cell harvesting and isolation technique yields extremely high numbers of stem cells. In reviewing outcomes data, treatment cell numbers appear to correlate with treatment success. Our cells are actually in a type of “soup” called Stromal Vascular Fraction (SVF), which are stem cells bathed in a rich mixture of natural growth factors. Some indications appear to respond better to stem cells that are super-enriched with growth factors created by administering Platelet Rich Plasma (PRP) to the patient. PRP is derived from a patient’s own blood. No foreign substances or medications are added to the stem cells.

Why do patients request stem cell treatments?

Many have been told that they require surgery or other risky treatments for their ailments and are looking for non-invasive options. Some have heard about the compelling testimonials about stem cells in the media and on various websites. Regeneris Medical does not believe in claims or testimonials since our work is still investigational but we are a resource for patients who need access to regenerative care. Regeneris Medical gives a choice to those informed patients who seek modern regenerative therapy.

A Network of Providers

Collaboration is key when working in a field that is constantly developing in research and application. At Regeneris Medical, we connect physicians and patients to create communication that is crucial to patient care, while expanding our knowledge of regenerative medicine. We seek to enable providers to offer their patients a wider range of services, and working together in developing treatment options for conditions where few currently exist.
