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

Smad-4 and Smad-7 are key in hair follicle development, with other Smads being less important.

Botulinum toxin has potential for treating various skin conditions and improving wound healing.

Oral retinoids are effective for treating severe skin disorders but have reversible side effects and risks for pregnant women.

P-cadherin is important for hair growth and health, and its problems can cause hair and skin disorders.

Experts say proper treatment and sensitivity are important for women's facial skin issues like acne and unwanted hair.

Hyaluronic acid and versican are important for skin healing and hair growth and might help in regenerative medicine.

Ovol2 is crucial for hair growth and skin healing by controlling cell movement and growth.

Sebocytes play a key role in controlling androgen levels in human skin.

Targeting androgen receptors could be a promising way to treat skin disorders with fewer side effects.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Signaling pathways are crucial for hair growth in goats.

DHEA acts like a male hormone on rat skin glands and doesn't turn into female hormones there.

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

Dermal papilla cells help wounds heal better and can potentially grow new hair.

The proteins transthyretin and megalin are more present in the growth phase of hair, suggesting they might affect hair health and growth.

Frog skin cells need the protein desmoplakin for proper development and cell layer formation.

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

The study found that sweat glands contain different types of stem cells that help with healing and maintaining healthy skin.

Mutations in Gasdermin A3 cause skin inflammation and hair loss by disrupting mitochondria.

Epidermal stem cells could lead to new treatments for skin and hair disorders.

Inositol and arginine solutions improve hair follicle health and turnover.

Aging causes skin stem cells to work less effectively.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Tiny particles called extracellular vesicles could help with skin healing and hair growth, but more research is needed.

Scientists created a long-lasting stem cell line from human hair that can turn into different skin and hair cell types.

Skin varies in thickness, color, and features due to complex genetic and cellular processes.

Active transdermal technologies in cosmetics help deliver skin treatments effectively, but their safety and effectiveness depend on skin type and treatment choice.

Mice with a Gsdma3 gene mutation have thicker skin and longer hair follicle openings due to increased β-catenin levels.
