Figure 6: Localization of proliferating (BrdU+, blue) endothelial (Cd34+, brown) cells lining the lateral mesometrial sinusoids of Day (A) 7.5 and (B) 8.5 IS tissue. Numbers above scale bars are in microns. Global linear adjustments of the brightness were made on the photomicrographs to more accurately represent what was seen on the slides under the microscope. All sections in photomicrographs are oriented mesometrial (MM) and anti-mesometrial (AM) regions down and up, respectively. Arrows denoteexamples of BrdU+CD34+ proliferating endothelial cells.
