FIG. 2.

Fetal tolerance is maintained in OVA-bred OT-II mice. The average number of viable and resorbing fetuses in B6-bred and OVA-bred OT-II mice at gd5.5, 10.5, 13.5, and 17.5 is shown with the SEM. For gd5.5, 10.5, 13.5, and 17.5, n = 7, 6, 6, and 7, respectively, for B6-bred OT-II mice, and n = 7, 6, 9, and 8, respectively, for OVA-bred OT-II mice. Significant differences in the number of viable or resorbing fetuses between B6-bred and OVA-bred at the same gestational day were determined using a Student t-test (none detected).
