AIRE protein, defective in APECED patients, is found in skin and hair cells and interacts with cytokeratin 17.

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.

EGFR signaling is crucial for skin and hair health, and targeting it could help treat skin diseases and cancer.

Citrulline in certain skin tumors suggests they mimic hair growth, helping distinguish them from other cancer types.

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

The cyst had unusual keratin spherules and resembled bone marrow.

Retinoids can help treat skin disorders by improving the skin's outer layer.

CRET therapy affects inflammation in skin cells by changing cytokine levels and activating certain proteins.

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

Keratin injections in mice can stimulate hair growth and might help treat hair loss.

Implanted special stem cells from hair follicles helped heal wounds faster and with less scarring in mice.

The study created a mouse model to better understand hair follicle stem cells' role in hair growth and repair.

Inactive hair follicle stem cells help prevent skin cancer.

Atoh1 expression can create new Merkel cells in the skin.

Adult hair follicle cells can create new hair follicles from corneal cells with the right support.

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

Mice with human skin protein K8 had more skin problems and cancer.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

Epidermal stem cells show promise for future dermatology treatments due to ongoing advancements.

Stem cells can create hair follicles, potentially treating permanent hair loss, and healthy skin and hair depend on mitochondrial function and special fats.

HPV8 causes hair follicle stem cells to grow, leading to skin lesions.

Different keratin types have unique amino acid patterns that are evolutionarily conserved.

Keratin gene regulation is similar across mammals, affecting hair follicle differentiation.

Keratin fibrils in hair form and stop growing at specific points in the follicle.

LRIG1 is linked to better survival in Merkel cell carcinoma.

Removing integrin α3β1 from hair stem cells lowers skin tumor growth by affecting CCN2 protein levels.

Major histocompatibility antigens are found in specific skin cells and structures, but not in sweat glands.

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.

One type of progenitor cell can maintain normal skin in mice.
