Binding of the Dolichos biflorus agglutinin (DBA) to endometrial apical luminal epithelium. Tissues were at
(a) proliferative,
(b) early secretory,
(c) mid secretory,
(d) mid-late secretory,
(e) late secretory phase.
Binding in the lumnal epithelium appears (d) at the end of the receptive window, approximately 9-10 days after ovulation. In glandular epithelium, DBA binding is also regulated, but the increase occurs earlier, in the mid secretory phase of the cycle (Jones et al.,1998).
