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.

Skin stem cells can help improve skin repair and regeneration.

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

The conclusion is that grasping how cells determine their roles through evolution is key, with expected progress from new research models and genome editing.

Maintaining DNA integrity in stem cells is crucial to prevent aging and cancer.

Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.

Cannabinoid receptor-1 signaling is essential for the survival and growth of human hair follicle stem cells.

miR-133a-3p and miR-145-5p help goat hair follicle stem cells differentiate by controlling NANOG and SOX9.

Special fiber materials boost the healing properties of certain stem cells.

Aging causes skin stem cells to work less effectively.

Retinoids increase steroid sulfatase activity in leukemia cells through RARα/RXR and involves certain pathways like phosphoinositide 3-kinase and ERK-MAP kinase.

Too much β-catenin activity can mess up the development of mammary glands and make them more like hair follicles.

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