The University of Utah Has an excellent website on learning how epigenetics works. It shows how signals are sent between cells, a vital form of communication that keeps the community we call a human body working correctly. These communications come from our parents when we are conceived and continue into old age. Stem cells receive signals to become a heart cell or muscle cell or bone cell. This changes the epigenetics of this cell and all of its children forever. The community of cells tries to adapt to the ever-changing environment. These changes cause our cells to try to change as well to better cope with the environment. Sometimes the changes are good and sometimes not so good for us. What is your epigenetics doing?
