Melatonin receptors in hair follicles help regulate hair growth and could treat hair loss.

Mice with more Flightless I protein grew back their claws better after amputation.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

The study created a new method to test drugs that affect hormone processing in skin.

Age-related hair loss is linked to the decline and dysfunction of hair follicle stem cells.

A device was made in 2008 to measure hair loss severity. Other findings include: frizzy mutation in mice isn't related to Fgfr2, C/EBPx marks preadipocytes, Cyclosporin A speeds up hair growth in mice, blocking plasmin and metalloproteinases hinders healing, hyperbaric oxygen helps ischemic wound healing, amniotic membranes heal wounds better than polyurethane foam, rhVEGF165 from a fibrin matrix improves tissue flap viability and induces VEGF-R2 expression, and bFGF enhances wound healing and reduces scarring in rabbits.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Human skin cells can create new hair follicles when transplanted into mice.

Mesenchymal stem cells help improve wound healing by reducing inflammation and promoting skin cell growth and movement.

Human hair follicle dermal cells can effectively replace other cells in engineered skin.

The experiment showed that human skin grown in the lab started to form early hair structures when special cell clusters were added.

Certain human skin cells marked by CD44 and ALDH are rich in stem cells capable of long-term skin renewal.
