hair follicles

Skin moles that sprout thick, long hairs produce signaling molecules that stimulate hair follicle stem cells to initiate new hair growth. This discovery may make baldness a thing of the past.

Corticosterone interferes with signaling in the skin that normally activates hair follicle stem cells, possibly explaining the link between stress and hair loss.

In mice, the fight-or-flight response overactivates the cells, causing a drop in their numbers, which leads to loss of hair color.

Normal hair growth can lead to infection during cancer treatment.

Neutrophil extracellular traps may hold clues to the cause of skin lesions in patients with a painful condition called hidradenitis suppurativa.

When hair follicle stem cells lose their protein-based death cue, they take on a new role helping to repair wounds in skin.

Under certain conditions, skin organoids including hair follicles can be generated from mouse pluripotent stem cells, researchers report.

In a developing chicken embryo, skin cells pull on each other, forming multicellular mounds that eventually turn into properly-spaced feathers.
