Sex-change Mice Research Could Help Humans, Say Scientists
Published:29 Jul.2018 Source:The Guardian
Scientists have turned male mice into females by snipping out strands of their DNA in work that could shed light on sexual development disorders which arise in humans. The male mice grew ovaries and female genitalia instead of the more conventional male anatomy after researchers removed small chunks of DNA from the animals’ genetic code.
The findings could help explain why people with XY chromosomes who are missing similar strands of DNA can go on to develop female sex organs, the scientists say. Males are typically born with X and Y chromosomes, while females have two Xs.
