Human eggs grown in lab for the first time by scientists!
Scientists at the University of Edinburgh have said they have succeeded in growing human eggs in the laboratory for the first time, offering new hope for fertility treatments. Experts believe the latest development could not only help the understanding of how human eggs develop, but open the door to a new approach to fertility preservation for women at risk of premature fertility loss such as those undergoing chemotherapy or radiotherapy.
While the process has previously been achieved with mice, it has proved difficult with human eggs. “It’s very exciting to obtain proof of principle that it’s possible to reach this stage in human tissue. But that has to be tempered by the whole lot of work needed to improve the culture conditions and test the quality of the oocytes [eggs],” said Prof Evelyn Telfer, one of the researchers on the project.
“But apart from any clinical applications, this is a big breakthrough in improving understanding of human egg development,” she said. In the journal ‘Molecular Human Reproduction’, the researchers describe how they took ovarian tissue from 10 women in their late twenties and thirties and, over four steps involving different cocktails of nutrients, encouraged the eggs to develop from their earliest form …read more
