Chimera (mythology) (that does not occur with depictions of male lions). Sighting the Chimera was an omen of storms, shipwrecks, and natural disasters (particularly volcanoes). While there are different genealogies, in one version the Chimera mated with her brother Orthrus and was the mother of the Sphinx and the Nemean lion (others have Orthrus and their mother, Echidna, mating; most attribute all to Typhon and Echidna). The Chimera finally was defeated by Bellerophon with the help of Pegasus, at the command of King Iobates of Lycia, after terrorizing Lycia and nearby lands. Since Pegasus could fly, Bellerophon shot the Chimera from the
Chimera (genetics) embryo selectively and not the other. For example, subsets of blastomeres can be used to give rise to chimera with specified cell lineage from one embryo. The Inner Cell Mass of a diploid blastocyst for example can be used to make a chimera with another blastocyst of eight-cell diploid embryo; the cells taken from the inner cell mass will give rise to the primitive endoderm and to the epiblast in the chimera mouse. From this knowledge, ES cell contributions to chimeras have been developed. ES cells can be used in combination with eight-cell-and two-cell-stage embryos to make chimeras and exclusively
