WebIn healthy tissues, the processes of mitosis and differentiation are tightly regulated. This is how the body ensures that only the correct number of cells is produced. The body has 2 methods for controlling the rate of cell proliferation: Growth factors; Contact inhibition; stimulate mitosis and/or cellular differentiation. WebThe research from the University of Illinois shows how much our DNA encodes these repair mechanisms. The health of our DNA affects how we age. Cell injury can occur anywhere in the cell—membranes, mitochondria, or the nucleus. Repair mechanisms exist everywhere to make sure these systems operate without hiccups.
