Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

LGR5 helps maintain corneal cell characteristics and prevents unwanted changes by controlling specific cell signaling pathways.

mTOR signaling helps activate hair stem cells by balancing out the suppression caused by BMP during hair growth.

Topical drugs and near-infrared light therapy show potential for treating alopecia.

Cyclosporine A may help treat hair loss by blocking a protein that inhibits hair growth.

Sox2-positive dermal papilla cells have unique characteristics and contribute more to skin and hair follicle formation than Sox2-negative cells.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.
