Fig. 2. Loss of Cx43 expression in the uterus of the Cx43
conditional-knockout mouse. (A,B) Uterine sections from
Cx43fl/fl (control) mice show prominent Cx43 expression in
the stromal cells surrounding the embryo. (C,D) Uterine sections
from Cx43d/d (conditional knockout) mice show efficient
ablation of Cx43 in uterine stromal cells. E denotes implanted embryo.
