Researchers at The University of Texas Health Science Center at Houston have demonstrated in rats that transplanting genetically modified adult stem cells into an injured spinal cord can help restore the electrical pathways associated with movement.
In spinal cord injury, demyelination, or the destruction of the myelin sheath in the central nervous system, occurs. The myelin sheath, produced by cells called oligodendrocytes, wraps around the axons of nerves and helps speed activity and insulate electrical conduction. Without it, the nerves cannot send messages to make muscles move
