The study concluded that both estrogen and androgen receptors, which decrease with age, are linked to skin aging and may be hormonally regulated.

Ingenol mebutate gel changes gene expression related to skin development and immune response in actinic keratosis.

Mice with autoimmune hair loss showed signs of heart problems.

Higher miR-34a levels and the A variant of the MIR-34A gene are linked to increased risk and severity of alopecia areata.

Air pollution (PM10) increases skin inflammation and aging by reducing collagen and may trigger a repair response in skin cells.

DNA methylation changes are linked to hair growth cycles in goats.

Scientists made stem cells that can grow hair by adding three specific factors to them.

Extracts from three Polynesian plants were found to promote hair growth by affecting cell growth and gene expression related to hair.

Aging reduces skin cell renewal and defense against germs due to TGFbeta, but blocking TGFbeta could help restore these functions.

Honokiol helps protect skin from damage and aging caused by cigarette smoke.

PTHrP is important for bone formation and may be targeted for osteoporosis treatment and longevity therapies.

Eating selenium-rich rice improved antioxidant activity and signs of aging in mice.

Cow placenta extract has strong antioxidant effects and can delay skin aging in mice.

Lipocalin-Type Prostaglandin D2 Synthase (L-PGDS) is a protein that plays many roles in the body, including sleep regulation, pain management, food intake, and protection against harmful substances. It also affects fat metabolism, glucose intolerance, cell maturation, and is involved in various diseases like diabetes, cancer, and arthritis. It can influence sex organ development and embryonic cell differentiation, and its levels can be used as a diagnostic marker for certain conditions.

The conclusion is that the cornea has two types of stem cells, with Lrig1+ cells being key for renewal in aging corneas, independent of CD44.

Skin health and repair depend on the signals between skin stem cells and their surrounding cells.

Stress can cause early aging in certain skin cells, leading to problems with hair growth.

SOX4 is crucial for the development of melanoma.

Oestrogens help maintain healthy skin, heal wounds, and may protect against skin aging and cancer.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.
