In a small patch of skin no bigger than an inch, there are millions of cells all performing duties, like protecting us from bacteria and sensing temperature. A portion of them are melanocytes, a type ...
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.
Hair follicle stem cells (green) mobilize and expand (white) to help repair the skin’s barrier by differentiating into epidermal lineages (red). When a child falls off her bike and scrapes her knee, ...
The leaf outer epidermal cell wall acts as a barrier against pathogen attack and desiccation, and as such is covered by a cuticle, composed of waxes and the polymer cutin. Cutin monomers are formed by ...
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 ...
Researchers in Japan are exploring a future where the body itself becomes a health monitor, no screens or batteries required.
Perhaps best known as a immune-system boost or antidote to scurvy, vitamin C has been found to rejuvenate aging skin by reactivating genes responsible for cell growth. By promoting DNA demethylation, ...
A vitamin commonly found in fresh fruits and vegetables could help slow one of the visible signs of aging: thinning skin. A new study has found that nourishment with vitamin C boosts epidermal ...
