“…In all these studies, treatment of uterine flushings by dialysis, lyophilization, fractionation, storage, or adjustment to a given protein concentration was involved. In most cases, best development occurred in unfractionated uterine flushings (El-Banna & Daniel, 1972b;Maurer & Beier, 1976;Beier et ai, 1983 Guilbert-Blanchette & Lambert (1978) found almost the same percentage of rabbit morulae developed into blastocysts in flushings derived from 'oestrous' or pseudopregnant rabbits of different times after hCG.…”

“…Although various developmental stages and criteria have been examined, supplementation of culture media with uterine secretions is consistently reported to improve development of cul¬ tured rabbit embryos (Gulyas et ai, 1969;El-Banna & Daniel, 1972a, b;Maurer & Beier, 1976;McCarthy et ai, 1977;Guilbert-Blanchette & Lambert, 1978;Beier et ai, 1983).

Rabbit morulae and blastocysts were cultured in conventional culture media [Ham's F10 or BSM II supplemented with bovine serum albumin (BSA) or serum] or in Ham's medium supplemented with synchronous or asynchronous uterine flushings, mostly for 2 days, and afterwards investigated by light and electron microscopy and by autoradiography. Ultrastructure and cell proliferation differed considerably between cultured embryos and noncultured controls. Cultured embryos displayed more dead cells. They were developmentally retarded (predominance of smooth endoplasmic reticulum rather than the age-specific rough endoplasmic reticulum, mitochondria still round to ovoid shaped) and showed nonspecific signs of cells damage (swollen mitochondria and Golgi complex vesicles, increased number of lysosomes). All these features were also present in embryos grown in uterine flushing-supplemented media, but were less pronounced. Cell damage and impaired cell proliferation had affected trophoblast cells more than embryoblast cells. Endoderm could be differentiated only if culture had been started with blastocysts--not with morulae--and seems to require uterine secretions. No significant ultrastructural differences were observed between embryos cultured in synchronous or in asynchronous uterine flushings. Present results indicate that cultured preimplantation rabbit embryos deviate clearly from those grown in vivo and maintain, for some time, a better cellular structure--and probably function--in the presence of uterine flushings than in conventional culture media. Specific abnormal morphologic features related to a particular medium could not be identified.
