The development decades and the new international economic order were, in part, chimeric or exercises in rhetoric.

Since this discovery occurred in 1999, ES cells have become a key tool in the generation of specific chimeric mice.

The general methods for creating chimeric mice can be summarized either by injection or aggregation of embryonic cells from different origins.

This process allows for sperm to be in constant supply when the female produces an egg, so that the chimeric fish is able to have a greater number of offspring.

In August 2003, researchers at the Shanghai Second Medical University in China reported that they had successfully fused human skin cells and rabbit ova to create the first human chimeric embryos.
