The number of embryos in uterine flushings of day 4 pregnant mice

Genotype	No. of plug-positive mice	No. of mice with embryos	Total no. of embryos*	Total no. of blastocysts (%)	Total no. of morula (%)
Tsg101f/f	8	6	32	26 (81.25)	6 (18.75)
Tsg101d/d	9	6	30	13 (43.3)	17 (56.7)

* Mice received 2.5 IU of eCG followed by 2.5 IU hCG 48 h later and were individually caged with stud males to induce mating. The next morning, a mouse with a visible vaginal plug was designated to be on day 1 of pregnancy. Mice were sacrificed at 11 AM on day 4. One uterine horn from each mouse was flushed and the other horn was subjected to histological analysis
