(CNN) – Stem cell research can run the gamut from Nobel Prize-winning scientists to hucksters in lab coats making a buck off desperate, seriously ill people. The results of one new study may be less than hoped for, but the science is sound: The study concluded that injecting stem cells into the spinal cords of patients with amyotrophic lateral sclerosis is safe in most, though not all, cases. Unfortunately, the procedure provided no benefit to patients, though it caused substantial pain to two of the study participants.
