Artificial 'embryos' created in the lab

Scientists have created "artificial embryos" using stem cells from mice, in what they believe is a world first.

The University of Cambridge team used two types of stem cells and a 3D scaffold to create a structure closely resembling a natural mouse embryo.

Previous attempts have had limited success because early embryo development requires the different cells to coordinate with each other.

embryos   ['embrɪəʊz]

scaffold  [ˈskæfəʊld]

coordinate  [kəʊ'ɔ:dɪneɪt]
