Beard cells, unlike scalp cells, produce growth factors in response to testosterone, which may explain differences in hair growth.

Possible new treatments for common hair loss include drugs, stem cells, and improved transplants.

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.

Stem cells, especially from fat tissue and Wharton's jelly, can potentially regenerate hair follicles and treat hair loss, but more research is needed to perfect the treatment.

Canine hair follicles have stem cells similar to human hair follicles, useful for studying hair disorders.

Mouse amnion can turn into skin and hair follicles with help from certain cells and factors.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.

Human skin can provide stem cells for tissue repair and regeneration, but there are challenges in obtaining and growing these cells safely.

Hair restoration surgery effectively treats hair loss with natural-looking results, using techniques like stem cells and platelet-rich plasma.

Wnt/ß-catenin signaling is crucial for regulating skin stem cells and hair growth, with the right levels and timing needed for proper function.

A hydrogel made from pig fat helps wounds heal faster by regenerating skin fat cells.

The document concludes that understanding dermal papilla cells is key to improving hair regeneration treatments.

Testosterone can slow hair growth in adult monkeys, but a blocker called RU 58841 can counteract this and potentially help hair regrow.

Injury changes how hair follicle stem cells behave, depending on the hair growth stage.

Minoxidil may help treat hair loss by reducing inflammation-related gene activity in skin cells.

Hair follicle studies suggest that maintaining telomere length could help treat hair loss and graying, but it's uncertain if mouse results apply to humans.

Softer hydrogel surfaces help maintain hair growth-related functions in skin cells.

Collagen and TGF-β2 help maintain hair cell shape and youthfulness.

Cells from certain embryo parts can induce head formation in another embryo, involving complex signaling pathways.

MAD2B slows down the growth of skin cells that are important for hair development by interacting with TCF4.

Keratin injections can promote hair growth by affecting hair-forming cells and tissue development.

GDNF helps grow hair and heal skin wounds by acting on hair stem cells.

The Hairless gene is crucial for hair cell development, affecting whether skin cells become hair or skin and oil gland cells.

Scoparone may help stimulate hair growth by increasing stem cell-related proteins in skin cells.

Scientists found the best time to transplant human stem cells for hair growth is between days 16-18 when they have the right markers and growth potential.

Dermal papilla cells are key for hair growth and color, influencing hair type and size, and their interaction with stem cells could help treat hair loss and color disorders.

Exosomes from dermal papilla cells help hair follicle stem cells grow and survive.

Adipose-derived stem cells help heal burns but need more research.
