Gamma rays did not change hair follicle density but increased white and hypopigmented hairs in mice.

Overexpression of sPLA2-IIA in mouse skin reduces hair stem cells and increases cell differentiation through JNK/c-Jun pathway activation.

Hair growth environment recreated with challenges; stem cells make successful skin organoids.

Bird foot scales develop differently and can repair but not fully regenerate due to the lack of specialized stem cell areas.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

Dermal cells are key in controlling hair growth and could potentially be used in hair loss treatments, but more research is needed to improve hair regeneration methods.

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

Collagen peptides from marine and bovine sources may help prevent hair loss by affecting hair follicle stem cells differently.

Older skin has higher cancer risk due to inflammation and stem cell issues.

Blood-derived CD34+ cells speed up healing, reduce scarring, and regrow hair in skin wounds.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

Stem cells are crucial for wound healing and understanding their role could lead to new treatments, but more research is needed to answer unresolved questions.

K42 and K124 keratins are only found in horse hoof lamellae.

The "Punch Assay" can regenerate hair follicles efficiently in mice and has potential for human hair regeneration.

Different human hair follicle stem cells grow at different rates and respond differently to a baldness-related compound.
