The skin has multiple layers and cells, serves as a protective barrier, helps regulate temperature, enables sensation, affects appearance, and is involved in vitamin D synthesis.

Cadmium chloride pollution can cause skin disorders, speed up aging, and prevent hair growth.

Tiny particles from 3D-grown skin cells speed up wound healing by promoting blood vessel growth.

Activating β-catenin in mammary cells leads to changes that cause early-stage abnormal growths similar to skin structures.

DNA methylation is essential for skin and hair follicle development, and could be a target for treating skin diseases.

Skin aging reflects overall body aging and can indicate internal health conditions.

Radiotherapy can cause skin fibrosis, which is often overlooked and needs better treatment and evaluation.

Exosomal miRNAs from stem cells can help improve skin health and delay aging.

The study provides insights into hair growth mechanisms in yaks.

Horse skin has a layered epidermis, a dermis with hair follicles, sweat and sebaceous glands, and is supplied by small arteries.

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.
