One of the key goals in developmental and reproductive biology has been achieved this week which could have incredible implications on both this planet and others. Life has been created in a Petri dish.
In a paper published just this week in Nature, Japanese researchers have been able to grow mouse eggs entirely In vitro. Fibroblasts (skin cells which produce collagen) were reprogrammed to make eggs.
While it is true that cells have been reprogrammed to different types of cell in the past. Creating eggs is much more tricky. Eggs are the ultimate stem-cell, able to create all the bits necessary to an organism from raw genetic blueprints. They are far more flexible than stem cells.
This is very solid work and an important step in the field
