Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.

The enzyme steroid sulfatase is linked to breast cancer and other conditions, and inhibitors are being developed for treatment.

The guidelines suggest lifestyle changes, diet adjustments, and personalized medication to manage dyslipidemia and reduce heart disease risk.

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

The Rotterdam Study found risk factors for elderly diseases, links between lifestyle and genetics with health conditions, and aimed to explore new areas like DNA methylation and sensory input effects on brain function.

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

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

Changing how mesenchymal stromal cells are grown can improve their healing abilities.

Microspheres about 1.5 micrometers in size can best penetrate hair follicles, potentially reaching important stem cells.

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.

Some drugs can cause rare but potentially deadly skin reactions, and early treatment and avoiding the drug again are key.

The Rotterdam Study aims to understand disease causes in the elderly and has found new risk factors and genetic influences on various conditions.

Polymeric nanoparticles show promise for treating skin diseases.

New nanofiber technology improves wound healing by supporting cell growth and delivering treatments directly to the wound.

Teriflunomide helps reduce multiple sclerosis symptoms and is safe for most patients.

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

The guidelines advise against using testosterone and DHEA in women for most conditions due to safety and effectiveness concerns, but suggest considering testosterone for postmenopausal women with low sexual desire.

Wnt1/βcatenin signaling is crucial for heart repair after injury.

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

Future hair loss treatments should aim to extend hair growth, reactivate resting follicles, reverse shrinkage, and possibly create new follicles, with gene therapy showing promise.

JAK inhibitors are effective in treating various immune-related diseases, not just rheumatoid arthritis.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

Tiny pollution particles called PM2.5 can harm skin cells by causing stress, damage to cell parts, and cell death.

Noggin is necessary to start the hair growth phase in skin after birth.

Androgens can both increase and decrease hair growth in different parts of the body.

Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

Metformin helps manage polycystic ovary syndrome by improving insulin resistance and ovulation, but more research is needed on its full effects.

Use minoxidil for hair loss; finasteride and dutasteride for men, dutasteride for women.
