Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

Fingerprints form uniquely before birth due to specific genetic pathways and local signals.

Type XVII collagen helps control skin cell growth and could be a target for anti-aging treatments.

Rats can't grow new hair follicles after skin wounds, unlike mice, due to differences in gene expression and response to WNT signaling.

Some hair protein genes evolved early and were adapted for use in hair follicles.

A protein called sFRP4 from skin cells stops the development of pigment-producing cells in hair.

Substances from fat-derived stem cells can promote hair growth and counteract hormone-related hair loss by activating a key hair growth pathway.

P-cadherin is crucial for hair follicle pigmentation but not skin pigmentation.
