The group observed that, at the cellular level, one of the side effects of the diet was an expansion of hair follicle stem cells, leading to increasing hair follicle growth and retention rates. (sciencedaily.com)
Using a nuclear protein expressed in follicle stem cells (FSCs), the researchers found that castor, which plays an important role in specifying which types of brain cells are produced during embryonic development, also helps maintain FSCs throughout the life of the animal. (sciencedaily.com)
What's more, they identified Cas as a critical, tissue - specific target of Hh signaling, which not only plays a key role in maintaining follicle stem cells but also assists in the diversification of their progeny. (sciencedaily.com)
