Cell types responsible for causing goosebumps are also important for regulating the stem cells that regenerate hair follicles and hair.
Melanocyte stem cells from human hair follicles that carry CD34 have the ability to turn into glial cells. The CD34+ stem cells can regenerate myelin, both on neurons and in mouse models with a genetic defect that prevents the formation of healthy myelin sheaths. The findings could have positive implications for the treatment of demyelinating diseases, such as Multiple Sclerosis.
NIH researchers have identified a specific type of sensory neurons which become activated as a result of pulling a single hair.
Researchers implicate KROXO20, a gene associated with neuron development, and SCF in hair graying and balding. They believe the findings could answer additional questions about human aging.
Compared to our other senses, scientists don’t know much about how our skin is wired for the sensation of touch....
