Scientists grow whole model of human embryo without sperm or egg

New Delhi, Sep 8 (PTI) Scientists have grown human embryo like structures without using sperm, eggs or a womb, an advance that could help reveal the causes of many birth defects and types of infertility.

A research team at the Weizmann Institute of Science in Israel created the complete models of human embryos from stem cells cultured in the lab – and managed to grow them outside the womb up to day 14.

The research, published in the journal Nature, shows that these synthetic embryo models had all the structures and compartments characteristic of this stage, including the placenta, yolk sac, chorionic sac and other external tissues that ensure the models’ dynamic and adequate growth.
