Blastocysts from estrogen-stimulated mice tend to be very sticky, a characteristic which can be correlated with estrogen-induced enzyme activation and changes in the surface coat of the trophoblast cells. The blastocyst surface coat was investigated using colloidal ironPrussian blue stain. In addition, the activity of tyrosine aminotransferase was assayed(More)

INTRODUCTION The trophoblastic giant-cell transformation of mouse blastocysts (Duval, 1891; Dickson, 1963) is blocked by ovariectomy carried out on the fourth day of gestation (Dickson, 19666)Such blocked blastocysts have a greater overall length and a shorter inner cell mass, and hence a larger blastocoele, thanuntransformed blastocysts from mice that have(More)
