Rats can't grow new hair follicles after skin wounds, unlike mice, due to differences in gene expression and response to WNT signaling.

Cattle skin has leptin which might control skin and hair growth.

Hair keratins evolved from ancient proteins, diversifying through gene changes, crucial for forming claws and later hair in mammals.

A specific gene variant causes severe skin issues and increases infection risk, requiring careful medical monitoring.

Laminin 332 is essential for normal skin cell behavior and structure.

Claudin expression changes help the skin respond to injury.

RSPO1 mutations in certain patients lead to skin cells that don't develop properly and are more likely to become invasive, increasing the risk of skin cancer.

Cell polarity signaling controls tissue mechanics and cell fate, with complex interactions and varying pathways across species.

Scientists found markers called CD34 and CD200 that help identify stem cells in mouse and human hair follicles.

Keratin protein production in cells is controlled by a complex system that changes with cell type, health, and conditions like injury or cancer.

Hormones and stretching both needed for nipple area skin growth in mice.

Special proteins are important for skin balance, healing, and aging, and affect skin stem cells.

Lacking cyclin D3 reduces skin cancer growth without affecting normal skin cell growth.

Acne treatment with isotretinoin increases the presence of p53, a protein, in skin and oil glands, which may help reduce acne severity.

MicroRNA-148a is crucial for maintaining healthy skin and hair growth by affecting stem cell functions.
