Fewer endothelial cells proliferate in Irx3^LacZ/LacZ implantation sites. (A, B) Endothelial cell proliferation within implantation sites was evaluated using immunofluorescence co-staining for proliferation marker, Ki67 (green), and endothelial cell marker, CD31/PECAM (red) (DAPI, nuclear stain, blue) in wild type (A) vs Irx3^LacZ/LacZ (B) uteri. Boxes in A–B are shown at higher magnification in A′-B′; L: uterine lumen. Boxes in A′-B′ are shown at higher magnification in insets. Yellow arrowheads indicate examples of Ki67 stain within endothelial cells.
