Fat cells help recruit healing cells and build skin structure during wound healing.

A protein from certain immune cells is key for new hair growth after skin injury in mice.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

Tiny pollution particles called PM2.5 can harm skin cells by causing stress, damage to cell parts, and cell death.

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

Stem cell niches are crucial for regulating stem cell renewal and differentiation, and understanding them can help in developing regenerative therapies.

Hair follicle development and microbes help regulatory T cells gather in newborn skin.

Capsaicin, found in chili peppers, can slow down hair growth by affecting skin cells and hair follicles.

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

A substance called DKK-1 increases in balding areas and causes hair cells to die when exposed to DHT.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Stem cell niches support, regulate, and coordinate stem cell functions.

Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.

Using CDK inhibitors on rats showed a reduction in chemotherapy-caused hair loss, but later experiments could not repeat these results.

Aging causes skin stem cells to work less effectively.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

Macrophages help heal nerves by aiding the maturation of Schwann cells and are important for nerve repair.

The conclusion is that Treg-targeted therapies have potential, but more knowledge of Treg biology is needed for effective treatments, including for cancer.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.

Fat cells in the skin help start healing and form important repair cells after injury.

Finasteride and minoxidil are effective for hair regrowth, while treatments for alopecia areata have varying success and continuous treatment is necessary.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

The research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

Thyroid hormones help hair grow, reduce hair loss, and increase hair pigment.

Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.

Too much Smad7 can cause serious changes in skin tissues, including problems with hair growth, thymus shrinkage, and eye development issues.

Skin's Regulatory T cells are crucial for maintaining skin health and could be targeted to treat immune-related skin diseases and cancer.
