Los Angeles, CA, USA – Lizards can regrow severed tails, making them the closest relative to humans that can regenerate a lost appendage. But in lieu of the original tail that includes a spinal column and nerves, the replacement structure is an imperfect cartilage tube. Now, for the first time, a USC-led study in Nature Communications describes how stem cells can help lizards regenerate better tails.
West Lafayette, IN, USA – Most strokes happen when an artery in the brain becomes blocked. Blood flow to the neural tissue stops, and those tissues typically die. Because of the locations of the major arteries in the brain, many strokes affect motor function. Some affect vision, however, causing patients to lose their vision or find it compromised or diminished. A research team led by Purdue University’s Alexander Chubykin, an associate professor of biological sciences in the College of Science, in collaboration with the team led by Gong Chen at Jinan University, China, has discovered a way to use gene therapy to turn glial brain cells into neurons, restoring visual function and offering hope for a way to restore motor function.
