These stem cells are called Human Spinal Stem Cells (HSSC) and have been engineered from the spinal cord of a single fetus electively aborted after 8 weeks of gestation. The tissue was obtained with the mother's consent. The cells will be transplanted into the ALS patient's spinal cord after laminectomy, an operation that removes bone surrounding the spine. After the spinal cord is exposed, a device manufactured for this purpose will be mounted onto the patient and will hold a syringe filled with the cells. The syringe will have a needle attached and the needle will enter the spinal cord at 5-10 locations injecting the cells. The device will minimize trauma to the spinal cord by the needle by making the puncture precise and steady and injecting the material at a slow and steady speed.
