At the Regenexx Blog site is a letter from a Registered Nurse who has Multiple Sclerosis. The drugs for MS do little to stop the progression of the disease and they have remarkably bad side effect. On top of that they are very expensive. Despite some exceedingly robust results with animals models with a form of MS and stem cell treatments, and human clinical trials with a patient’s own mesenchymal stem cells, the FDA has yet to budge because according to your FDA cells = drugs and they get to regulate them into the ground.
This letter from the nurse really nails it on the head and shows how the FDA’s policy is a) crap, and b) actively hurting sick people. Read about it here, and then write your Congressperson.
