... compact cell masses stick in the vaginal furrows. Epithelial surface cells are highly irregular and bulging with their microvilli covered surfaces in the vaginal lumen. This study represents the first comprehensive description of alterations on the surface ultrastructure of a marsupial vagina during...

...J.M. Old; L. Selwood; E.M. Deane The development of the lymphoid tissues of a model marsupial, the stripe-faced dunnart, has been described from birth to weaning, a period of 2.5 months. At birth the lymphoid tissues, including the thymus, lymph nodes and mucosa-associated lymphoid tissues, were...

... contribute to the ECM by increasing the area of plasma membrane for synthesis of a hyaluronan-like ECM. As in other marsupials, the precedence of cell-zona adhesion over cell-cell contacts prevents morula formation. The earliest cell-zona contacts appear when microvilli contact the zona in the uterine zygote...

...Nicholas Casey; Lynne Selwood The aim of the present study was to investigate the role of the marsupial shell coat in embryonic development because it may be a potential target for immunocontraceptive control of the brushtail possum. Conceptuses from 52 female possums were collected between 1995...

...Christian Regli; Annetrudi Kress The vaginal complex of marsupials differs from that of eutherians. Cervices open separately in a sinus vaginalis or cul-de-sac. Two lateral vaginae adjoin the sinus vaginalis and fuse at the level of the urethra opening and form the sinus urogenitalis. During...

...Regula Wick; Annetrudi Kress Ultrastructural changes in the cervical epithelium related to the estrous cycle have been studied in the South American marsupial Monodelphis domestica . The two cervices protrude with prominent papillae into the sinus vaginalis. At times of simple columnar at others...

...Regula Wick; Annetrudi Kress Ultrastructural changes in the endometrium associated with the oestrous cycle were studied in the South American marsupial Monodelphis domestica. The most conspicuous changes include the height and the differentiation of the uterine luminal and glandular epithelium...

...A. Kress; N.E. Merry; L. Selwood The timetable of oogenesis in Sminthopsis macroura is accelerated like in other marsupials showing relatively early maturation of the female. On the day of parturition (day 0) migration of primordial germ cells to the indifferent gonads has been completed...
