Researchers identify new architecture and mechanism in the human sperm.

In male fertility normal sperm cells have an oval-shaped head with a cap-like covering called the acrosome. The acrosome contains enzymes that break down the outer membrane of an egg cell, allowing the sperm to fertilize the egg. 486 more words

Aberrant Lipid Metabolism in the Forebrain Niche Suppresses Adult Neural Stem Cell Proliferation in an Animal Model of Alzheimer’s Disease

Bhaskar Chanda Stem Cell Hamilton et al. identify deregulation of niche fatty acid metabolism as a mechanism of disease-induced stem cell impairment. They show that interfering with oleic acid signaling or synthesis rescues NSC proliferation in a mouse model of Alzheimer’s, revealing a potential approach to promote NSC-mediated brain function and repair. 13 more words

Rho-Signaling-Directed YAP/TAZ Activity Underlies the Long-Term Survival and Expansion of Human Embryonic Stem Cells

Bhaskar Chanda Stem Cell Ohgushi et al. show that a regulatory pathway involving Rho, YAP/TAZ, and the actin cytoskeleton that is specific for the pluripotent state enables human embryonic stem cells to undergo long-term survival and expansion in culture. 13 more words
