The temporal and spatial parameters of oestrogen-induced increases in RNA, protein and DNA synthesis were investigated autoradiographically in mice undergoing experimental diapause. The tritiated precursors, uridine, amino acid hydrolysate and thymide, were instilled into uterine lumen for a 15 minute pulse at various times after subcutaneous oestrogen(More)
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)
