The bald truth—altered cell divisions cause hair thinning

Hair grows from stem cells residing in hair follicles. During aging, the capability of hair follicles to grow hair is successively lost, leading to hair thinning and ultimately hair loss. In a new study, researchers from ...

3D lab skin for chemicals testing, research and repair

A model system that recreates full-thickness human skin should allow more effective testing of pharmaceuticals and cosmetics, while avoiding the need for animal tests. The system effectively models the development, cellular ...

How an egg cell's 'operating manual' sets the stage for fertility

Recently published work from Carnegie's Allan Spradling and Wanbao Niu revealed in unprecedented detail the genetic instructions immature egg cells go through step by step as they mature into functionality. Their findings ...

Fine-tuning stem cell metabolism prevents hair loss

A team of researchers from Cologne and Helsinki has discovered a mechanism that prevents hair loss: hair follicle stem cells, essential for hair to regrow, can prolong their life by switching their metabolic state in response ...

Researchers identify microRNA that shows promise for hair regrowth

Researchers from North Carolina State University have identified a microRNA (miRNA) that could promote hair regeneration. This miRNA—miR-218-5p—plays an important role in regulating the pathway involved in follicle regeneration, ...
