Scientists created keratinocyte cell lines from human hair that can differentiate similarly to normal skin cells, offering a new way to study skin biology and diseases.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

The conclusion is that genetic differences affect how the cochlea heals after hair cell loss, which may challenge the creation of hearing loss treatments.

β1 integrin is essential for the survival, growth, and movement of human epithelial progenitor cells.

Testosterone replacement therapy significantly improved sexual interest and function in HIV+ men.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Gene network oscillations inside hair stem cells are key for hair growth regulation and could help treat hair loss.

High proliferative activity and peripheral invasion indicate malignancy in canine sebaceous gland tumors; the term 'epithelioma' should be updated for clarity.

The study concluded that the developed models are effective for studying hair growth mechanisms and testing new treatments.

The growth of the Epstein-Barr virus in the patient's cells was linked to the worsening of her lymphoma.

The review found that basal cell carcinomas on the scalp are not more aggressive than those in other locations.

The calcineurin/NFAT pathway plays a significant role in the development and growth of a type of skin cancer called cutaneous squamous cell carcinoma.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

Dermal-epidermal interactions are crucial for hair growth and maintenance.

Merkel cells stabilize nerve endings in the skin, and they change independently of each other.

Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.

Wnt5a may contribute to psoriasis by reducing skin cell growth, blocking skin cell maturation, and increasing inflammation.

Finasteride may increase depression by reducing brain cell growth.

Men are more likely to have larger basal cell carcinomas and squamous cell carcinomas, while women have more superficial basal cell carcinomas and tumors on their legs and central face.
