Artificial mouse embryo created from stem cells for 1st time
Cambridge University scientists have managed to create a structure resembling a mouse embryo in culture. A self-developing embryo was created using two types of stem cells, the body's 'master cells' and a 3D scaffold, an extracellular matrix to grow it. Embryo development studies can explain why more than two out of three human pregnancies fail at early stages, biologists said.
