Last year, Japanese researchers announced that the first human patient would be treated with induced pluripotent stem cells in an attempt to reverse a degenerative eye condition called macular degeneration that leads to vision loss.
Now, a team of scientists headed by biologists at UC San Diego has discovered how induced pluripotent stem (iPS) cells, which are derived from an individual’s own cells, could be programmed to avoid rejection from the immune system.
Their findings, published online ahead of print in the journal Cell Stem Cell, show that iPS cells can differentiate or change into various types of functional cells with
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.
