The FDA has the authority to regulate stem cell products in the United States.

Today, doctors habitually use stem cells that return from bone marrow or blood in transplant procedures to treat patients with cancer and disorders of the blood and system.

With restricted exceptions, the investigational product should additionally bear a radical federal agency review method as investigators prepare to work out the security and effectiveness of the product in well-controlled human studies, known as clinical trials. The federal agency has reviewed several somatic cell products to be used in these studies.

As a part of the FDA’s review, investigators should show however every product is going to be factory-made that the federal agency will make certain acceptable steps area unit being taken to assist assure the product’s safety, purity, and efficiency. The federal agency additionally needs ample information from animal studies to assist in appraising any potential risks related to product use.

Some clinics could not suitably advertise somatic cell clinical trials while not submitting associate degree IND. Some clinics additionally could incorrectly advertise that federal agency review and approval of the somatic cell medical aid is mindless. however once clinical trials don’t seem to be conducted below associate degree IND, it implies that the federal agency has not reviewed the experimental medical aid to assist make certain it’s fairly safe. therefore, use caution concerning these treatments.

The only stem cell-based product that area unit FDA-approved to be used within the US carries with it blood-forming stem cells (hematopoietic ancestor cells) derived from twine blood.

For instance, attendees at a 2016 federal agency public workshop mentioned many cases of severe adverse events. One patient became blind because of associate degree injection of stem cells into the attention. Another patient received a funiculus injection that caused the expansion of a spinal neoplasm.

Other potential safety issues for unverified treatments include:

The ability of cells to manoeuvre from placement sites and alter into inappropriate cell sorts or multiply, failure of cells to figure evidently, and the growth of tumours.
