A type of opsin known as neuropsin is expressed in the hair follicles of mice and synchronize the skin’s circadian clock to the light-dark cycle, independent of the eyes or brain, University of Washington researchers report. “This is the first functional demonstration of opsin photoreceptors outside the eye directly controlling circadian rhythms in a mammal,”… Read more

Skin cells taken from patients with a rare genetic disorder are up to ten times more sensitive to damage from ultraviolet A (UVA) radiation in laboratory tests, than those from a healthy population, according to new research from the University of Bath. It is hoped that the work, which has involved designing a brand new… Read more

How fibroblasts develop into fat cells, and the pathway that causes this process to cease as people age, has been identified by University of California San Diego School of Medicine researchers and colleagues. Dermal fibroblasts are specialized cells deep in the skin that generate connective tissue and help the skin recover from injury. Some fibroblasts… Read more

Differences in the cells that give skin its resilience and strength during wound repair may explain why individuals heal differently, according to a new Yale study. Fibroblasts, the cells that form the protein structure beneath the surface of the skin, were once thought to be fairly uniform in their function. However, the new study found… Read more

The first lab-grown skin tissue complete with hair follicles has been cultured by researchers at Indiana University School of Medicine. The skin model, developed using stem cells from mice, more closely resembles natural hair than existing models and may prove useful for testing drugs, understanding hair growth, and reducing the practice of animal testing. Although… Read more
