From the WSJ:
“Scientists from the University of Texas Southwestern Medical Center at Dallas and others have shown they can keep certain types of cells living forever, including those from the breast, skin, retina and, recently, the colon, by adding telomerase to keep telomeres intact or repair those that became too short. Now researchers are studying how telomerase-based therapies could help repair damaged cells and play an major role in cancer research.”
