A computer model, quantitative fate mapping, looks back in the developmental timeline to trace the origin of cells in a fully grown organism.

Blocking a specific gene in people in the early stages of cardiomyopathy could halt the development of scar tissue and delay heart failure.

Humans lose them after embryonic development, unlike some animals. New Harvard research offers potential insights into why.

Microglia, immune cells disguised as brain cells, are known as the janitors of the brain. Dialing up their usual duties just enough could provide an avenue to treat neurodegenerative disease.

New research indicates that "crosstalk" between stem cells in tumors and their environment leads to a loop that can promote cancer.

Can underproduction of key immune cells contribute to Alzheimer's? A new study suggests the answer is yes.

These immature connections may explain how the adult brain is able to form new memories and absorb new information.

Researchers harness new pooled, image-based screening method to probe the functions of over 5,000 essential genes in human cells.

New research digs into why blood stem cell transplants are so effective as a therapy for multiple sclerosis.

Inflammation is a complicated and important part of how the immune system responds to threats to the body. But when the inflammatory response goes awry, it can lead to serious problems.
