Blood vessels in the lungs produce signals that activate the regeneration of alveoli—the tiny cavities through which blood takes in oxygen and releases carbon dioxide.
A previously overlooked group of cells has been shown to be essential in helping adult stem cells multiply and revitalize damaged tissue.
By switching off a single gene, researchers have created mice that behave much like people with obsessive-compulsive disorder. The animal model could help scientists design new therapies for the debilitating condition.
Endothelial cells keep blood stem cells dividing healthily in a lab dish much longer and more effectively than previous methods of growing the cells.
Researchers have devised a new method that increases the number of blood vessel-forming cells they can make from human embryonic stem cells.
A protein previously thought to identify only colon cancer stem cells is actually prevalent throughout primary colon tumors.
Scientists have succeeded in reprogramming adult stem cells from the testes of male mice into functional blood vessels and contractile cardiac tissue.
HHMI researchers discover that cancers are spread to specific organs by non-malignant bone marrow cells.
Investigadores del HHMI descubren que los cánceres se diseminan a órganos dianas mediante células de la médula ósea que no son malignas.
