Using radiation to make mice's hair turn gray helps study and find ways to prevent or reverse hair graying.

Fat cells are important for tissue repair and stem cell support in various body parts.

Lung repair involves both dedicated and flexible stem cells, important for developing new treatments.

Nail stem cells and Wnt signaling are important for fingertip regeneration but not sufficient for regenerating more complex limb structures.

A special hydrogel helps heal skin without scars and regrows hair.

Transit-amplifying cells are crucial for tissue repair and can contribute to cancer when they malfunction.

The review concludes that innovations in regenerative medicine, tissue engineering, and developmental biology are essential for effective tissue repair and organ transplants.

The gene p53 is crucial for removing damaged cells to allow for healthy tissue renewal.

WNT10A helps esophageal cancer cells spread and keep renewing themselves.

HSPGs help control stem cell behavior, affecting hair growth and offering a target for hair loss treatments.

Planarian regeneration begins with a specific gene activation caused by injury, essential for healing and tissue regrowth.

Alk1 in specific cells is crucial for proper nerve branching and hair function.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

S100A4 and S100A6 proteins may activate stem cells for hair follicle regeneration and could be potential targets for hair loss treatments.

Steroid sex hormones activate matriptase in prostate cancer cells but not in breast cancer cells.

The study found that a specific area of the hair follicle helps start hair growth by reducing the blocking effects on certain cells and controlling growth signals.

Certain signals are important for reducing specific chemical markers on hair follicle stem cells during rest periods, which is necessary for healthy hair growth.

Gata6 is important for protecting hair growth cells from DNA damage and keeping normal hair growth.

Vitamin D and calcium are important for quick and effective skin wound healing.

Glypican-1 is important for blood vessel growth in hair follicles and could help treat hair loss.

RT1640 treatment reverses gray hair and promotes hair growth in mice.
