At a certain points they exit the cycle and stop dividing. We mimic this stage by starving the cells. That makes them stop growing and puts them in a hibernating state. A hibernating cell is much easier to work with, but what we think is important is that its genetic information now has a different structure, so it is easier to take it back to the early state and reprogram it. We discovered that by accident.
Serendipity probably happens more often than people think.
It is ideas and overseeing which is exciting to me. We probably have eight or nine scientists working on cell cycles now. This number will probably double in the next six months to 12 to 24 people. For a man of such profound accomplishment, you have much humility. It is serendipity.
