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

Stem cells are crucial for skin repair and new treatments for chronic wounds.

Tofacitinib is safe and effective for severe alopecia areata, but hair loss may return 2 months after stopping treatment.

Insulin resistance and obesity are key factors in the development and worsening of polycystic ovary syndrome, and lifestyle changes are important for managing it.

Minoxidil and finasteride treat hair loss in men, while minoxidil treats hair loss in women.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Interferon alfa-2a is effective for treating cutaneous T cell lymphoma but has significant side effects.

PGD2 stops hair growth and is higher in bald men with AGA.

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

Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

Most women with excess hair growth have an underlying hormonal issue, often treated with medication and hair removal methods.

Alopecia areata is likely an autoimmune disease with unclear triggers, involving various immune cells and molecules, and currently has no cure.

Androgens may cause hair loss by increasing TGF-beta1 from scalp cells, which inhibits hair cell growth.

Regulatory T-cells are important for healing and regenerating tissues in various organs by controlling immune responses and aiding stem cells.

Skin cells produce and activate vitamin D, which regulates skin functions and supports hair growth.

Alopecia areata is an autoimmune condition causing hair loss due to the immune system attacking hair follicles, often influenced by genetics and stress.

Regenerated fully functional hair follicles using stem cells, with potential for hair regrowth therapy.

Bone Morphogenetic Proteins (BMPs) help control skin health, hair growth, and color, and could potentially be used to treat skin and hair disorders.

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.

The peptide GHK-Cu helps heal and remodel tissue, improves skin and hair health, and has potential for treating age-related inflammatory diseases.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Vitamin D and its receptor regulate skin functions like cell growth, immunity, hair cycle, and tumor prevention.

Early diagnosis and individualized treatment improve outcomes for Congenital Adrenal Hyperplasia.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

Minoxidil works better for female hair loss, but cyproterone reduces scalp oiliness and causes menstrual issues.
