Adult esophageal cells can start to become like skin cells, with a key pathway influencing this change.

PRGF treatments increased hair number and thickness in people with hair loss, with more injections leading to better results.

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

Wnt5a may slow down hair growth in mice.

Skin stem cells remember past inflammation, helping them respond better to future injuries and possibly aiding in treating skin issues.

Gray hair can potentially be reversed, leading to new treatments.

Hairless mammals have genetic changes in both their protein-coding and regulatory sequences related to hair.

NF-κB signaling is crucial in many diseases and can be targeted for new treatments.

TLR2 is important for hair growth and can be targeted to treat hair loss.

Eating less can improve stem cell function and increase lifespan.

CD4+ skin cells may be precursors to basal cell carcinoma.

DNA methylation is essential for skin and hair follicle development, and could be a target for treating skin diseases.

The skin's dermal layer contains true stem cells with diverse functions and interactions that need more research to fully understand.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Blocking Prostaglandin D₂ may help treat hair loss.

Transplanting melanocyte stem cells from hair follicles can effectively treat vitiligo.

Hair ages and thins due to factors like inflammation and stress, and treatments like antioxidants and hormones might improve hair health.

The document concludes that pig iPSCs show promise for transplant therapies and the field is advancing in controlling cell behavior for biology and medicine.

Dorper sheep's wool shedding is linked to specific genes and pathways, which may help understand human hair growth.

Pilose antler extracts help hair growth by activating hair follicle stem cells.

Different types of fibroblasts play specific roles in wound healing and cancer, which could help improve treatments.

Hair follicle stem cells help skin heal and grow during stretching.

Modifying certain signals in the body can help wounds heal without scars and regrow hair.

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

Hair aging is caused by stress, hormones, inflammation, and DNA damage affecting hair growth and color.

Keratinocytes and adipose-derived stem cells can effectively heal difficult skin wounds.

Vav2 changes how hair follicle stem cells' genes work as they age, which might improve regeneration but also raise cancer risk.

The mTOR signaling pathway is crucial for hair health and targeting it may lead to new hair loss treatments.

Skin's uneven surface and hair follicles affect its stress and strain but don't change its overall strength, and help prevent the skin from peeling apart.

Shi-Bi-Man activates hair follicle stem cells and promotes hair growth by changing lactic acid metabolism and other cellular processes.
