Artificial Embryo Grown in a Dish from Two Types of Stem Cells

March 2, 2017

(New Scientist) – Artificial mouse embryos grown from stem cells in a dish could help unlock secrets of early development and infertility that have until now evaded us. Magdalena Zernicka-Goetz at the University of Cambridge and her team made the embryos using embryonic stem cells, the type of cells found in embryos that can mature into any type of tissue in the body. The trick was to grow these alongside trophoblast stem cells, which normally produce the placenta. By growing these two types of cell separately and then combining them in a special gel matrix, the two mixed and started to develop together.
