The F.D.A. reported actions against two large stem cell clinics and a biotech company calling them “unscrupulous actors” in regenerative medicine.
This clinics used to extract stem cells from bone marrow, blood or fat and develop into many different types of cells in order to repair or replace tissue damaged by disease, injury or aging.
But so far, the F.D.A. has approved only a few stem-cell products.
The F.D.A. commissioner Dr. Scott Gottlieb announced that there is no proof that these methods are actually work.
As a result of stem cell treatment in one of these clinics one woman went blind and two others suffered severe, permanent eye damage.
