Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

Adam10 enzyme is crucial for healthy skin and proper Notch signaling.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

Thymosin β4 promotes hair growth by activating stem cells in hair follicles.

Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.

Wool follicles are complex, involving interactions between different cell types and structures.
