Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.

Cultured dermal papilla cells can regenerate hair follicles and sustain hair growth.

Wounds can regenerate hair in young mice, but this ability declines with age, offering insights for improving tissue regeneration in the elderly.

Dermal stem cells help regenerate hair follicles and heal skin wounds.

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

The new matrix improves skin regeneration and graft performance.
