I was just thinking if I was in phase 1 trials with these endometrial cells for critical limb ischemia ,I would have a few patients with also spinal cord injuries , and the bystander effect could also cure this injury ,the company could also state not only critical limb ischemia was cured but also the spinal cord was healed as well ,just thinking ,it may not travel that far ,these cells probable have to be injected in the damaged area .
