Innate immunity genes in hair follicle stem cells might have new roles beyond traditional immune functions.

A rat had a cyst similar to a hair follicle structure.

Activin increases skin tumor formation, skin Tregs help hair growth, lymph-node removal doesn't improve melanoma survival, cells can revert to stem cells in wound healing, and skin bacteria produce peptides that may treat infections.

Nestin-positive cells are important for hair follicle regeneration in alopecia areata.

Regulatory T cells protect hair follicle stem cells by maintaining immune privilege in the skin.

Basal cell carcinomas in mice can start from hair follicle stem cells and other skin cell types, depending on signaling levels.

A woman's masculine features were caused by a rare ovarian tumor that produced male hormones.

Early recognition and evaluation of nevus sebaceus are crucial to detect and manage potential cancerous changes.

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.

Alopecia areata is reversible because hair follicles can regenerate due to stem cells.

Large corneum layer cells can cover wounds effectively.

Nestin is found in hair follicle progenitor cells, linking them to neural stem cells.

There are two types of stem cells in rodent hair follicles, each with different keratin proteins.

Different types of inactive melanocyte stem cells exist with unique characteristics and potential to develop into other cells.

Hair structure worsens as tumors grow in mice.

Removing a testicular tumor in a dog reduced its aggressive behavior and skin problems.

Rushton's hyaline bodies form from hair keratin and blood substances.

Cell junctions are crucial for healthy skin by supporting sebaceous gland function and sebum production.

Sebum production in sebaceous glands is similar to hair growth, involving cell development and degeneration.

The hair follicle bulge is an important area for adult stem cells involved in hair growth and repair, with potential for medical use needing more research.

K31 can identify clear secretory cells in human sweat glands.

Chrysanthemum zawadskii extract helps hair grow by stimulating hair cells.

Cancer can hijack the body's cell repair system to promote tumor growth, and targeting this process may improve cancer treatments.

Fertility-preserving surgery can help women with early-stage Sertoli-Leydig cell tumors conceive naturally.

Rhabdomyosarcoma is the most common head and neck cancer in children, requiring complex treatment.

Sox2-positive cells determine specific hair follicle types in mammals.

A rare skin tumor with extra hair growth was found and safely removed from a 27-year-old woman.

Skin cells can naturally limit the growth of cancerous changes by balancing cell renewal and differentiation.

Ber‐EP4 marks cells related to the secondary hair germ in hair follicles.

Trichogerminoma is a rare, benign skin tumor from hair cells, with a small risk of becoming cancerous.
