Paraplegic rats walk again after receiving human stem cells
Three weeks after being injected with engineered tissue containing human stem cells, paraplegic rats were found to walk independently and regain sensory perception, according to an Israel-based study. Among implanted paraplegic rats, 42% showed an improved ability to support weight on their hind limbs and walk, while 75% responded to stimuli to the hind limbs and tail, researchers reported.
