UTHealth research shows modified adult stem cells may be helpful in spinal cord injury
Posted on February 27th, 2010 | by Stem Cell News |
Researchers at UTHealth 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. The results are published in today’s issue of the Journal of Neuroscience.
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.
The research team, led by Qilin Cao, M.D., principal investigator and associate professor of neurosurgery at UTHealth (The University of Texas Health Science Center at Houston), discovered that transplanted adult stem cells (oligodendrocyte precursor cells or OPC) from the spinal cord could become oligodendrocytes. The new cells helped restore electrical pathways of the spinal cord and therefore, function, in a process called remyelination.
