Latest Asymmetric cell division Stories
Recently biologists at the University of Massachusetts Amherst led by Wei-lih Lee have identified a new molecular player in asymmetric cell division, a regulatory protein named She1 whose role in chromosome- and spindle positioning wasn't known before.
Stem cells provide a recurring topic among the scientific presentations at the Genetics Society of America's 53rd Annual Drosophila Research Conference, March 7-11 at the Sheraton Chicago Hotel & Towers.
The accumulation of damaged protein is a hallmark of aging that not even the humble baker's yeast can escape. Yet, aged yeast cells spawn off youthful daughter cells without any of the telltale protein clumps.
From the valves in a human heart to the quills on a porcupine to the petals on a summer lily, the living world is as varied as it is vast. For this to be possible, the cells that make up these living things must be just as varied.
It took almost 10 years for Elaine Fuchs, Ph.D., a Howard Hughes Medical Institute investigator at Rockefeller University, to find a postdoctoral fellow who shared her curiosity for the direction of cell divisions in the skin.
Howard Hughes Medical Institute researchers have discovered a novel way in which the brain size of developing mammals may be regulated. They have identified a signaling pathway that controls the orientation in which dividing neural progenitor cells are cleaved during development.
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
