Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.

A substance called DKK-1 increases in balding areas and causes hair cells to die when exposed to DHT.

Pectin biosynthesis is essential for the growth of cotton fibers and Arabidopsis root hairs.

Scientists made working salivary glands in mice using bioengineered cells, which could help treat dry mouth.

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.

Blood vessels and specific genes help turn cartilage into bone when bones heal.

Vitamin D and its receptor regulate skin functions like cell growth, immunity, hair cycle, and tumor prevention.

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

Alopecia areata causes hair loss, has no cure, and various treatments exist.

Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.

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.

K6hf is a unique protein found only in a specific layer of hair follicles.

The HR protein helps hair grow by blocking a hair growth inhibitor, aiding in hair follicle regeneration.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Estrogen Receptor ß (ERß) is the main hormone controller in human skin and hair follicles, not Estrogen Receptor α (ERα) or the Androgen Receptor (AR).

Trichoscopy can diagnose female hair loss with high accuracy by looking for specific patterns in hair and scalp appearance.

Normal skin cell renewal doesn't need RAR signaling, but vitamin A-related skin thickening does.

Oxidative stress contributes to hair graying and loss as we age.

Particles around 100 nm can penetrate and stay in hair follicles without passing through healthy skin, making them safe for use in topical products and useful for targeted drug delivery.

Different ethnic groups have unique hair growth patterns, with African hair growing slower and less dense, Asian hair growing fast but sparse, and Caucasian hair being densest; men are more likely to experience hair loss than women.

Some drugs can cause skin, nail, and hair problems, which are important for healthcare professionals to recognize and report.

Tiny particles from stem cells help activate hair growth cells and encourage hair growth in mice without being toxic.

Targeting hair follicles can improve skin treatments and reduce side effects.

Researchers found that hair shedding happens mostly when new hair is growing and involves a unique process.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.

Thymosin β4 promotes hair growth by activating stem cells in hair follicles.

Antiandrogens affect androgen-dependent body functions and are used for various medical conditions, with some risks like fetus feminization, but new forms like 17α-propylmesterolone show promise for acne without systemic effects.

Androgens block hair growth by disrupting cell signals; targeting GSK-3 may help treat hair loss.
