Stem cells don't just become a part of the liver or the brain in a flash; it takes a complex molecular choreography and requires that specific genes be switched on and off at specific times. Some of these genes are regulated through a process by which proteins in the cell nucleus, called histones, are chemically modified by small "chemical marks" such as acetyl or methyl groups.
