Nerves are crucial for the regeneration of various body parts in many animals.

Melanocyte stem cells are crucial for skin pigmentation and have potential in disease modeling and regenerative medicine.

Improved understanding of stem cell mechanisms can enhance skin tissue engineering.

Special proteins are important for skin balance, healing, and aging, and affect skin stem cells.

Fat under the skin releases HGF which helps hair grow and gain color.

Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.

The new matrix improves skin regeneration and graft performance.

Low oxygen areas help maintain and protect blood stem cells by using a simple sugar breakdown process for energy and managing their activity levels.

Fat tissue under the skin affects hair growth and aging; reducing its inflammation may help treat hair loss.

Hair transplant surgery can rebuild muscle and nerve connections, allowing transplanted hairs to stand up like normal hairs.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

Scientists successfully grew new hair follicles in regenerated mouse skin using mouse and human cells.

Aging causes changes in scalp cells that can negatively affect hair health.

Epidermal stem cells use integrin β1 and α6 as markers and CD271+ cells help maintain skin health and heal wounds.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

The document concludes that understanding how adult stem and progenitor cells move is crucial for tissue repair and developing cell therapies.

Aging causes changes in the scalp that can affect hair growth and lead to older-looking hair in women.

PRP and cell therapies may help with hair loss, but more research is needed.

Calcium is important for stem cell function and maintenance, especially in blood and skin cells.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Using fat stem cells and blood cell-rich plasma together improves healing in diabetic wounds by affecting cell signaling.

Skin aging is caused by stem cell damage and can potentially be delayed with treatments like antioxidants and stem cell therapy.

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

Transplanted whisker follicles caused hair growth on the spine of mice.

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

Both immature and mature fat cells are important for hair growth cycles, with immature cells promoting growth and mature cells possibly inhibiting it.

Meis1 is crucial for skin health and tumor development.
