Different types of sun exposure damage skin cells and immune cells, with chronic exposure leading to more severe and lasting damage.

Activating β-catenin in mammary cells leads to changes that cause early-stage abnormal growths similar to skin structures.

Scientists created a 3D skin model to study a chronic skin disease and test treatments.

Platelet-rich plasma injections significantly improved hair regrowth and thickness in patients with hair loss.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

The document concludes that hair follicle regeneration involves various factors like stem cells, noncoding dsRNA, lymphatic vessels, growth factors, minoxidil, exosomes, and induced pluripotent stem cells.

Environmental factors, hormones, nutrition, and stress all significantly affect skin health and aging.

Aging changes sugar molecules on skin stem cells, which may affect their ability to repair skin.

Sweat gland development involves two unique skin cell programs and a temporary skin environment.

Caffeine improves hair growth, thickness, and reduces shedding.

Transethosomes improve drug delivery through the skin and show promise for treating various conditions.

ADAM 10 and ADAM 12 proteins are involved in different stages of hair growth and could be targets for treating hair disorders.

Metformin helps with menstrual cycles and insulin levels in PCOS but is less effective for hair growth, diabetes prevention, and weight loss, and may improve fertility and reduce diabetes risk.

Mice can correct hair follicle orientation without certain genes, but proper overall alignment needs those genes.

MSC-Exos can aid organ development and offer therapeutic benefits for various conditions.

cDermo-1 causes dense skin, feathers, and scales in chickens.

The ABCA4 gene protects hair follicle stem cells from toxic vitamin A byproducts.

Certain cells in the adult mouse ear come from cranial neural crest cells, but muscle and hair cells do not.

New hair loss treatments may include topical medications, injections, and improved transplant methods.

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

Aging slows wound healing due to weaker cells and immune response.

Retinoic acid-binding proteins in skin are regulated by β-catenin and Notch signalling.

Genes controlling hair growth and immune response are disrupted in male pattern baldness.

Heat and chemicals improve finasteride delivery to scalp and hair follicles, potentially enhancing treatment for hair loss.

Scientists found the best time to transplant human stem cells for hair growth is between days 16-18 when they have the right markers and growth potential.

Different types of skin cells play specific roles in development, healing, and cancer.

Different cell types work together to repair skin, and targeting them may improve healing and reduce scarring.

Human stem cells were turned into cells similar to those that help grow hair and showed potential for hair follicle formation.

The protein SLC1A3 is important for activating skin stem cells and is necessary for normal hair and skin growth in mice.

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