Here we report the dynamic, autonomous formation of the optic cup (retinal primordium) structure from a three-dimensional culture of mouse embryonic stem cell aggregates.

在本文中我们报告了视杯(视网膜原始细胞)结构在三维培养介质中的动态的、自发性的成形过程，该培养介质是由鼠胚胎干细胞聚集物组成。

These cells were also created using mouse cells, starting with mouse skin cells, and the comparison between what you get from a mouse cell that's transformed this way and an embryonic stem cell, they look to be very similar.

First came the remarkable work of Shinya Yamanaka at Kyoto University, who showed it was possible, by activating just four genes, to take a mature cell (he used a bit of skin but other cells would work) and turn it into the equivalent of an embryonic stem cell with the potential to become any other cell in the body of mouse or human.
