What's next?
Genetic engineering experts at the University of Cambridge have produced a "synthetic" mouse embryo without using egg or sperm cells.
The researchers believe their findings will one day help explain why many human pregnancies fail early in development and may even inform future efforts to create lab-grown organs for transplantation.in the lab, as well as how to create artificial but simplistic models of embryos or individual organs—advances that have helped overcome some of these obstacles.
