BMI1, a protein essential in the self-renewing cell divisions of adult stem cells, can be prevented from spawning potentially defective or misplaced cells that hinder tissue regeneration, according to a study in Nature Cell Biology. Researchers believe that the manipulation of BMI1 and other regulatory molecules may one day be useful in the development of techniques that need specialized cell development switches for the treatment of tissue damage brought about by injury, disease or aging.
