Amazing Potential of Stem Cells to Repair the Brain
My NewsBits are often about advances in stem cell research (1, 2, 3, 4). There is good reason – the recent advances in our understanding of stem cells make them a key component in efforts to heal the brain. This video shows the potential of stem cell-based therapy.
Dr. Siddharthan Chandran on TED Talk
For years, medical students have been taught incorrectly that the brain cannot repair itself. Recent exciting research on stem cells has definitely put that “dogma” to rest. In fact, the rapid pace of discoveries about the brain indicates that the future may be closer than you think. The brain actually does repair itself, just not enough. The repair the brain does do uses a natural reservoir of stem cells (pluripotent cells that have the potential to become any cell). Recent research has shown that we will be able add more stem cells to boost the natural repair of the brain and restore lost functions, even functions usually considered to be lost forever. In the video, Dr. Siddharthan Chandran hypothesizes that the added stem cells help repair the brain, not by acting themselves to do the repairs, but by activating more of the brain’s own stem cells.
