A mouse born from two fathers has lived to become an adult, marking a first in science history. Chinese scientists at the Chinese Academy of Sciences made this possible by modifying imprinting genes that control gene expression through techniques like gene deletion, region editing, and genetic base pair changes. “This work will help to address a number of limitations in stem cell and regenerative medicine research,” says Wei Li, who led the research team. What makes this special is that unlike some lizards and snakes that can reproduce without mating, mammals have always needed both male and female parents to … Continue reading Mouse with Two Fathers Reaches Adulthood in Scientific First
