When nutrients run low, hair follicle stem cells can stop making hair and help repair the skin instead. A drop in the amino ...

The skin acts as the body's first line of defense against external threats. However, as we age, the epidermis—the outermost layer of skin—gradually becomes thinner and loses its protective strength.

VC is known for its antioxidant properties in the skin and has been previously shown to boost collagen synthesis. Now, the same team of researchers has taken this a step further, using advanced ...

Retinoic acid, the active state of Vitamin A, appears to regulate how stem cells enter and exit a transient state central to their role in wound repair. Retinoic acid, the active state of Vitamin A, ...

Fluctuation in signal transduction pathways is frequently observed during mammalian development. However, its role in regulating stem cells has not been explored. Here we tracked spatiotemporal ERK ...

Tiny folds anchoring human skin, called 'rete ridges,' form soon after birth. They show an early-life window that could reshape aging.

Indiana University School of Medicine researchers have cultured the first lab-grown skin tissue complete with hair follicles. This skin model, developed using stem cells from mice, more closely ...
