Can one feel too attached? Does one need to let go to mature? Neural stem cells have this problem, too. As immature cells, neural stem cells must stick together in a protected environment called a niche in order to divide so they can make all of the cells that populate the nervous system. But when it's time to mature, or differentiate, the neural stem cells must stop dividing, detach from their neighbors and migrate to where they are needed to form the circuits necessary for humans to...

Findings offer new insights into neurologic development and regenerative therapies for neurologic disease Researchers at Columbia University Medical Center (CUMC) have identified a molecular pathway that controls the retention and release of the brain's stem cells. The discovery offers new insights into normal and abnormal neurologic development and could eventually lead to regenerative therapies for neurologic disease and injury. The findings, from a collaborative effort of the...

Combined, complimentary therapies have the ability to maximize the benefits of neural stem cell (NSC) transplantation for spinal cord repair in rat models, according to a study carried out by a team of Korean researchers who published in a recent issue of Cell Transplantation (20:9), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/. "When transplanted, neural stem cells have demonstrated their therapeutic potential to reverse complex pathological processes...

Lack of regulator can cause neural tube defects Researchers at the University of Colorado School of Medicine have found that lack of a specific gene interrupts neural tube closure, a condition that can cause death or paralysis. "The neural tube is the beginning of the brain and spinal cord," said the study's lead investigator Lee Niswander, Ph.D., professor of pediatrics at the CU School of Medicine. "A defect in the mLin41 gene doesn't allow the tube to close because not enough neural...

Testosterone, the primary male sex hormone, appears to have antidepressant properties, but the exact mechanisms underlying its effects have remained unclear. Nicole Carrier and Mohamed Kabbaj, scientists at Florida State University, are actively working to elucidate these mechanisms. They've discovered that a specific pathway in the hippocampus, a brain region involved in memory formation and regulation of stress responses, plays a major role in mediating testosterone's effects, according...

Research from a Kansas State University professor may make it easier to recover after spinal cord injury or to study neurological disorders. Mark Weiss, professor of anatomy and physiology, is researching genetic models for spinal cord injury or diseases such as Parkinson's disease. He is developing technology that can advance cellular therapy and regenerative medicine -- a type of research that can greatly improve animal and human health. "We're trying to build tools, trying to build...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
