The Skin Keeps Time Independent Of The Brain

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,” […]

How Dermal Fibroblasts Develop Into Fat Cells

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 […]

First Lab-grown Skin Tissue With Hair Follicles Cultured

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 […]
