摘要：

Eggs and embryos (up to the unilaminar blastocyst stage) were collected from grey short-tailed opossums, Monodelphis domestica, at known time intervals after mating. Some were fixed immediately for examination by light and electron microscopy while others were maintained in culture at 37-degrees-C in 5% CO2 in Ham's F10 medium containing foetal calf serum. Cleavage to the early blastocyst stage was obtained in vitro although most embryos displayed arrested development at the eight-cell stage. From gross morphological and ultrastructural observations a pattern of embryogenesis to the unilaminar blastocyst was constructed. Comparisons were made with the events of early development in other marsupials.
