Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Photodynamic therapy is the preferred treatment for skin precancer due to its effectiveness and safety.

Asiasari radix extract may be a potential treatment for melanoma because it selectively triggers cell death in melanoma cells by affecting p53 regulation.

BRG1 is essential for skin cells to move and heal wounds properly.

New methods have greatly improved our understanding of stem cell behavior and roles in the body.

The p53 protein helps control hair follicle shrinking by promoting cell death in mice.

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

Mice without Vitamin D receptors have hair growth problems because of issues in the hedgehog signaling pathway.

Erythropoietin helps hair grow and could be a potential treatment for hair loss.

TGF-alpha is present in sheep and ferret skin and may affect hair growth without directly stimulating cell proliferation.

CD201+ fascia progenitors are essential for wound healing and could be targeted for treating skin conditions.

Fish oil increased cell growth and macrophages in the skin but didn't affect COX-2 expression.

Nestin-expressing cells turn into a specific type of skin cell in hair follicles during development and in adults.

Fgf20 is important for the development and regulation of the cells that form the base of hair follicles.

The document concludes that skin stem cells are important for hair growth and wound healing, and could be used in regenerative medicine.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

Keratins are crucial for cell structure, growth, and disease risk.

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.

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.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

Substance P may worsen acne by increasing inflammation, but corticosteroids might help by reducing this effect.

Melanocyte precursors in human fetal skin follow a specific migration pattern and some remain in the skin's deeper layers.

Cysteine helps maintain keratin production in skin cells even when iron is low.

Skin-derived stem cells can become various cell types, including germ cell-like and oocyte-like cells.

ILK is essential for proper hair follicle development and structure.

Understanding how epigenetic regulation affects stem cells is key to cancer insights and new treatments.

The document concludes that stem cells and their environments are crucial for skin and hair health and have potential for medical treatments.

Inhibiting AP-1 changes skin tumor types and affects tumor cell identity.

Inhibiting AP-1 changes skin tumor types and affects tumor cell identity.

GATA6 is important for maintaining and differentiating cells in a key area of human skin.
