This study deals with the histochemistry of the
changing patterns of glycogen in the uterus and extra-embryonic membranes of the golden hamster (Mesocricetus
auratus Waterhouse). The uterus and extra-embryonic
membranes of the golden hamster representing days of
gestation from six to term were stained with periodic
acid-Schiff and Best's carmine....
The relationship between plasminogen activator (PA) production and cell stage, cell number and changes in overall diameter and zona pellucida thickness for bovine embryos developing in vitro was determined. Late morulae to blastocysts (n=80) were collected nonsurgically from naturally mated, estrous-synchronized and superovulated crossbred beef cows. Embryos were cultured, one...
