Androgens reduce BMP2, which weakens the ability of certain cells to help hair stem cells become different types of cells.

Melanocytes are important for skin and hair color and protect the skin from UV damage.

Clinicians should use social and prescription data to track trends in performance-enhancing drug use.

PCOS is linked to diabetes and insulin resistance, and managing AGEs may help treat related symptoms.

Eating less can improve stem cell function and increase lifespan.

PRP might help with hair growth and skin rejuvenation, but more research is needed to prove its effectiveness.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

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.

HDAC6 helps keep ovarian follicles dormant, extending female fertility.

A protein called EGFR protects hair follicle stem cells, and when it's disrupted, hair follicles can be damaged, but blocking certain pathways can restore hair growth.

Shell ginger contains kavalactones that promote hair growth and have anti-cancer, anti-inflammatory, and anti-obesity effects.

Acne can appear or persist in adulthood due to hormonal changes, external factors, or substance use, and requires appropriate treatment.

Grape seed extract is good for skin care, with antioxidant, anti-inflammatory, and anti-cancer effects.

A device was made in 2008 to measure hair loss severity. Other findings include: frizzy mutation in mice isn't related to Fgfr2, C/EBPx marks preadipocytes, Cyclosporin A speeds up hair growth in mice, blocking plasmin and metalloproteinases hinders healing, hyperbaric oxygen helps ischemic wound healing, amniotic membranes heal wounds better than polyurethane foam, rhVEGF165 from a fibrin matrix improves tissue flap viability and induces VEGF-R2 expression, and bFGF enhances wound healing and reduces scarring in rabbits.

Melatonin directly affects mouse hair follicles and may influence hair growth.

Activating β-catenin increases melanocytes and decreases Schwann cells.

Blocking the ATX-LPA pathway may improve insulin sensitivity and mitochondrial function in obesity.

Understanding how baby skin heals without scars could help develop treatments for adults to heal wounds without leaving scars.

Increased FGFR2b signaling, influenced by androgens, plays a role in causing acne.

Photobiomodulation therapy helps manage cancer treatment side effects but needs more research for optimization.

Adipokines affect skin health and could be targeted for treating skin diseases.

Hedgehog pathway inhibitors can treat certain aggressive cancers but face limitations like resistance and side effects.

Follistatin and LIN28B together improve the ability of inner ear cells in mice to regenerate into hearing cells.

The study found that analyzing certain cell signaling pathways is not a reliable method to tell apart two types of skin tumors.

Genetic defects in the glucocorticoid receptor gene can cause conditions with abnormal sensitivity to stress hormones, and other factors may also affect this sensitivity.

Vitamin D and calcium are important for skin stem cell function and wound healing.

Lower SMAD2/3 activation predicts more severe skin cancer.

Nitric Oxide has potential in medicine, especially for infections and heart treatments, but its short life and delivery challenges limit its use.

Integrin β1 is crucial for liver structure and function, preventing fibrosis.

Myristoleic acid helps hair growth by boosting cell growth and recycling processes in hair follicle cells.
