Stem Cell Epigenetics
As an organism grows and develops, carefully orchestrated chemical reactions activate and deactivate components of the genome at strategic times and in specific locations. Epigenetics is that the study of these chemical reactions and the factors that influence them. It is strongly believed that there are some signals at the epigenetic level that regulate the fate of the stem cells. Though all of the cells in our body contain the same genetic makeup. These genes are not necessarily active at all times, rather they are expressed at times when needed in a highly controlled fashion.
