Scientists Develop World's First 'Synthetic' Embryo With Brain & Beating Heart: Report
Cambridge University scientists have produced the world's first "synthetic" embryo with a brain and beating heart. The embryo was generated using mouse stem cells, which are similar to stem cells in the body and may develop into practically any form of cell. Researchers were able to encourage the stem cells to "speak" to each other by activating a certain set of genes and providing a particular environment for their interactions.
