Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

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

Anabolic steroids can build muscle and strength but have risks and need more research on their clinical benefits and side effects.

Keratins help protect cells, aid in cancer diagnosis, and influence cancer behavior and treatment.

Some wound-healing cells can turn into fat cells around new hair growth in mice.

Understanding phenotypic plasticity is crucial for developing effective cancer therapies.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

Human skin can make serotonin and melatonin, which help protect and maintain it.

Metformin helps with menstrual cycles and insulin levels in PCOS but is less effective for hair growth, diabetes prevention, and weight loss, and may improve fertility and reduce diabetes risk.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Human skin makes sexual hormones that affect hair growth, skin health, and healing; too much can cause acne and hair loss, while treatments can manage these conditions.

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

The conclusion is that certain cell interactions and signals are crucial for hair growth and regeneration.

Certain proteins, Lgr5 and Lgr6, are important markers of adult stem cells and are involved in tissue repair and cancer development.

Adult stem cells from rat whisker follicles can regenerate hair follicles and sebaceous glands.

Alopecia areata is an autoimmune condition causing hair loss, influenced by genetics, stress, and diet, and may be prevented by a high soy oil diet.

Epithelial-mesenchymal interactions control hair growth cycles through specific molecular signals.

The document concludes that insulin resistance is key in PCOS development and early treatment is crucial to prevent complications.

Exposure to too much androgen before birth might cause polycystic ovary syndrome later in life.

The document concludes that the fast-growing direct-to-consumer genetic testing market lacks sufficient regulation, posing risks to consumers due to questionable test quality and accuracy.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

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

The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.

Eph receptors and ephrins may be promising targets for treating diseases, but more understanding is needed for effective and safe therapies.

Mice lacking the PPARγ gene in their fat cells had almost no fat tissue, severe metabolic problems, and abnormal development of other fat-related tissues.

Different types of skin cells play specific roles in development, healing, and cancer.

Male and female bodies respond differently to stress, influenced by hormones and development stages, with implications for stress-related diseases.
