"A new study suggests that cells preparing to divide can reverse this process and return to a resting state, challenging long-held beliefs about cell division. If interrupted early in their preparation to divide, cells were able to halt the division process, known as mitosis. The finding, led by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and reported July 5, 2023, in Nature, could point toward more effective treatments to interrupt the process by which cancer cells divide quickly and spread. Finding  could point toward more effective treatments that could potentially prevent cancer relapse." more »
