Different skin stem cells help heal wounds, with hair follicle cells becoming more important over time.

The vitamin D receptor is essential for skin stem cells to grow, move, and become different cell types needed for skin healing.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Thyrotropin-Releasing Hormone helps heal wounds in frog and human skin.

Activin B improves wound healing and hair growth by helping stem cells move using certain cell signals.

Stem cells have great potential for improving wound healing, but more research is needed to find the best types and ways to use them.

Hydrogen peroxide can cause scars by changing healing processes and increasing certain protein levels.

Human alpha defensin 5 helps heal wounds, reduce bacteria, and grow hair on burned skin.

Prominin-1 expressing cells in the dermal papilla help regulate hair follicle size and communication but don't aid in skin repair.

Mice without collagen VI have slower hair growth normally but faster regrowth after injury.

Tannic acid helps wounds heal faster in rats by activating certain cell signals and reducing inflammation.

Disrupting Notch signaling in blood vessels increases scarring during wound healing in mice.
