how to control stem cells ?
White Blood cells Scientists at the University of bathtub have known however a cistron in fish is concerned in dominant stem cells. A new study from the cluster of academic Henry M. Robert Kelsh within the Department of Biology appearance at however a unique cluster of stem cells squa re measure controlled by mutations in a gene called parade. They identified a new set of stem cells in zebrafish, which eventually become skin pigment cells of different colours. Populations of pigment stem cells are formed in the embryonic stages of development, but are then dormant and don't mature into a final cell type until adulthood. This development is controlled by a range of factors called the "stem cell niche—including surrounding cell types, blood supply and signals from nerves. In parade mutants the zebrafish show large numbers of abnormally positioned pigment cells near the main blood vessels, lined up 'like soldiers on parade'. The Bath team's work de
