STEROIDOGENIC CAPABILITIES OF THE EARLY MOUSE EMBRYO K. E. Grube, F. C. Gwazdauskas, J. A. Lineweaver and W. E. Vinson Department of Dairy Science Virginia Polytechnic Institute and State University Blacksburg, Virginia 24061 Received 6-15-78 ABSTRACT Preimplantation embryos from ICR albino mice were used to determine progesterone and estradiol-17@ production during incubation in BMOC-2. Following culture of 40 embryos/culture at either the morula, early blastocyst or late blastocyst stages, progesterone and estradiol-176 contents were 192+27 and 82522 pg, 289+_50 and I.47246 pg and 157228 and 88523 pg, respec%vely, for incubated samples and 306268 and 89240 pg, 404263 and 125~44 pg, and 241254 and 86+39 pg, respectively for control samples. Although, there were signTficant stage of development and treatments effects (P
