Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

Human alpha defensin 5 helps heal wounds, reduce bacteria, and grow hair on burned skin.

QMSI is a valuable method for studying drug penetration in skin tissues.

Men are getting more facial fillers, and doctors should use different techniques and fillers for men's unique facial features to get natural results.

The two-step procedure of fat grafting followed by hair grafting improves scalp and facial scar correction.

Obesity can weaken the skin's ability to fight infections because fat cells stop and reduce the infection-fighting properties of nearby stem cells.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

Runx1 controls fat-related genes important for normal and cancer cell growth, affecting skin and hair cell behavior.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

Hyaluronic acid injections improve skin thickness and quality, protecting against aging in rats.

Women with more body hair tend to have thicker belly fat and more metabolic health issues.

Melatonin affects many body functions beyond sleep by interacting with specific receptors in various tissues.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Correct skin biopsy techniques are crucial to avoid misdiagnosis of skin diseases.

Skin grafts are effective for chronic leg ulcers, especially autologous split-thickness grafts for venous ulcers, but more data is needed for diabetic ulcers.

Advancements in creating skin grafts with biomaterials and stem cells are promising, but more research is needed for clinical application.

The model better predicts how water-loving and fat-loving substances move through the skin by including tiny pores and hair follicle paths.

Human skin can provide stem cells for tissue repair and regeneration, but there are challenges in obtaining and growing these cells safely.

Aging scalp skin contributes to hair aging and loss, and more research is needed to develop better hair loss treatments.

Unconventional lymphocytes are important for quick immune responses and healing of skin and mucosal barriers.

Melatonin treatment helps improve skin health in postmenopausal rats.

Transplanting growing hair follicles into scars can help regenerate and improve scar tissue.

Tissue expansion is a useful method for reconstructive surgery with good results and room for further enhancement.

Different stem cells have benefits and challenges for tissue repair, and more research is needed to find the best types for each use.

Radiation treatment causes skin fibrosis by increasing certain fibroblast subpopulations, but using a c-Jun inhibitor or fat grafting can reduce this effect.

Scientists can now create skin with hair by reprogramming cells in wounds.

Researchers created human hair follicles using a new method that could help treat hair loss.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.
