In line with the recommendations of an ECVAM workshop on reproductive toxicity, held in 1994, ECVAM initiated and funded a validation study of three in vitro embryotoxicity tests. In two of these assays, pregnant laboratory animals are used to obtain embryonic tissue — either primary embryonic cells in the mouse micromass (MM) test or embryos in the rat whole embryo culture (WEC) test. In contrast, in the embryonic stem cell test (EST) a permanent mouse embryonic stem cell line is used.
