Abstract

Blastocysts of C57BL/6 mice obtained either 2.5 or 3.5 days post-coitum (dpc) were examined for efficient microinjection after overnight in vitro culture. Incidences of zona-free embryos were much higher at 3.5 dpc after natural mating (1.05/mouse) and superovulation (2.83/mouse) than at 2.5 dpc after natural mating (0.05/mouse) and superovulation (0.01/mouse). By testing germ-line competency of gene-targeted J1 embryonic stem cells, superovulation and/or in vitro culture should be recommended for producing microinjectable blastocysts for production of high germ-line chimeras.
