rat에서 knockout이 2008년이 되어서야 가능해졌다고 하는데, mice에 비해 이렇게 늦게 시작된 이유가 무엇입니까?

    Most techniques for genetic manipulation, including random mutagenesis with a gene trap (retroviral-based and non-retroviral-based), gene knock-outs/knock-ins, and conditional mutations, depend upon the culture and manipulation of embryonic stem (ES) cells. Rat ES cells were only recently isolated and no demonstration of gene modification in them has been reported. Consequently, many genetic manipulation techniques widely used in the mouse are not possible in the rat.
