Scientists have created a 6-legged mouse embryo with an extra pair of hindlimbs at the expense of their external genitalia. But far from creating a monster, this rudimentary rodent provides important ...

Using the blastocyst complementation method, we produced rat embryonic stem (ES) cell-derived sperm in testicular hypoplasia mice and successfully generated rat offspring. This method can provide a ...

DOWNTOWN LOS ANGELES - For the first time in history, USC researchers have derived authentic embryonic stem (ES) cells from rats. This breakthrough finding will enable scientists to create far more ...

A rat embryonic stem cells derived lung generated within a mouse body stained with epithelial cells (labelled with E-cadherin, shown in gray), rat cells (shown in green), mouse cells (shown in red), ...

Rie Natsume and her collaborators have recently developed an innovative and cost-effective method for generating rats that inherit traits from embryonic stem (ES) cells. Unlike mouse ES cells, rat ES ...

Adding rat stem cells to a mouse embryo resulted in a ‘hybrid brain’ in which the rat cells stepped in to restore function when the mouse’s sense of smell was removed, new research has shown. It’s the ...
