()N A HUMAN BLASTULA RECOVERED FROM THE UTERINE CAVITY 4 DAYS AFTER OVULATION

A. T. HERTIG AND J. Rock

Anat. Rec., 94: 469, 1946

The specimen was recovered from a uterus removed surgically on the twenty-first day of a menstrual cycle previously ranging from 25 to 32 days duration.

Probable fertile coitus occurred 4:} days previously. Endometrium morphologically was characteristic of the eighteenth day, ovulation having occurred 4 days previously. The stigma of the recent corpus luteum was unhealed.


The free-lying blastula was obtained in Locke’s solution removed by pipette from the cavity of a submerged uterus opened completely at one side and partially across the fundus. The specimen was discovered with a binocular dissecting microscope using 10 diameters of magnification. Fresh, the specimen measured 190 x 150 micra but after fixation in Bouin’s fluid, begun 1 hour after removal of the uterus, it measured 175 x 124 micra. It was surrounded by a sticky, thick, transparent, refractile vitelline membrane which shrank during fixation.


Following dehydration and embedding in celloidin-parafiine, 15 perfect serial sections of 6 micra each were obtained by Dr. Chester Heuser. Nine blastomeres of varying size and shape were present: 5 containing 1 nucleus each, 3 with 2 nuclei each and 1 with 3 nuclei. Three of the single-nucleated blastomeres are in varying stages of mitosis. A segmentation cavity is just beginning to form.


Because of the presence of multinucleated blastomeres the specimen is probably not normal, although no other human specimen is available for comparison.
