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

Women look young for their age due to larger lips, less sun damage, and genes that prevent gray hair and wrinkles.

The document concludes that the exact way alcohol causes harm to fetal development is unknown, but it significantly affects nutrient transport to the fetus and a safe level of alcohol during pregnancy is not determined.

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

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Blocking COX, especially COX-2, in the skin can reduce inflammation and pain and may help prevent skin cancer.

Stem cell niches support, regulate, and coordinate stem cell functions.

Low iron levels may be linked to some types of hair loss in women.

Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.

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

Zinc is crucial for growth and health in rats.

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

Androgens can cause hair growth in some areas and hair loss on the scalp.

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

Tributyltin exposure causes sex changes, sterilization, and decline in the snail Ocinebrina aciculata, risking its extinction.

Male pattern baldness involves genetics, hormones, and needs better treatments.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Humans lost body hair relatively recently in evolution.

Effective treatments for male pattern baldness include oral finasteride and topical minoxidil, while topical minoxidil is best for female pattern baldness.

Congenital Adrenal Hyperplasia is a genetic disorder with two forms, causing symptoms like early puberty and severe acne, but can be identified through screening and treated with glucocorticoids.

Estrogen therapy can reduce skin aging but has cancer risks.

Stem cell self-renewal is complex and needs more research for full understanding.

Alopecia areata is an autoimmune disease causing patchy hair loss, often with other autoimmune disorders, but its exact causes are unknown.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

The WNT signaling pathway is important in many diseases and targeting it could offer new treatments.

Aging causes skin stem cells to work less effectively.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Young adults have about 230,000 tactile nerve fibers, decreasing 5-8% per decade with age.
