Researchers have shown that dangerous cysts, which form over time in polycystic kidney disease (PKD), can be prevented by a single normal copy of a defective gene.
<p>Clinicians often find limited success in treating patients with traumatic brain injury, a condition long linked to contact sports and military services. A new study, published April 4 in the journal <em>Cell Stem Cell</em>, may offer new clues to better solutions. Scientists found a protein, TDP-43, that appears to drive nerve damage right after injury. Moreover, blocking a certain cell surface protein can correct faulty TDP-43 and curb nerve death in mouse and human cells.</p>
Researchers can use the light naturally thrown off by biological specimens to better study the different states of stem cells in the nervous system, thanks to a tool developed at the University of Wisconsin–Madison, brightening their chances for stud
Researchers at the RIKEN Center for Developmental Biology say they have unraveled the mystery of why human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells undergo apoptosis (programmed cell death) when cultured in isolation, a discovery that promises new hope to sufferers of debilitating degenerative diseases.
It's an achievement with important implications for scientists studying the brain and working on treatments for a broad range of neurological and neur
