Frequently Asked Questions

+ 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. After you have a complete understanding of the potential risks and benefits for your recommended treatment and would like to explore this avenue of treatment, you can be considered for our cellular therapies. Of course, even though it’s a minimally invasive procedure, you will still need to be medically cleared to participate in 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.

+ Why do patients request stem cell treatments?

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


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 collaborating in developing treatment options for conditions where few currently exist.
