Bonita Springs, FL - A Southwest Florida doctor at the center of a controversy involving stem cells is making the case for the procedure. 

Dr. Zannos Grekos has not been able to perform a treatment involving bone marrow following the death of a patient years ago. State regulators imposed an emergency restriction on Dr. Grekos' medical license back in February.

On Wednesday, Bill Orr walked into the Regenocyte offices in Bonita Springs after spending a part of his life in a wheel chair. Orr underwent the procedure last year and credits it for changing his life.

"It was a dream come true. I always said that someday they are going to do something with stem cells", he said.

The treatment involved bone marrow and not blood which the FDA has not approved.

State regulators are expected to present their medical malpractice case in the woman's death in January.
