Growth factor expression stimulates endothelial cell (EC) proliferation. Fluorescent staining of mesenteries after injection of adenovirus-enhanced green fluorescent protein (Ad-EGFP) (control) or Ad-growth factors. Isolectin IB4-TRITC (red) stains ECs, Hoechst 33324 (blue) stains all mesenteric nuclei and antibodies to Ki67-AF488 (green) to detect proliferating cells. Overlaying of the stack images is used to calculate the number of proliferating endothelial cells (PECs). Images are triple stained with TRITC-streptavidin and biotinylated GSL lectin IB4 (ECs, red). Alexa Fluor 488-labeled goat antimouse immunoglobulin G and mouse monoclonal anti-Ki67 antibody (proliferating cells, green) and overlay. The PECs can be distinguished from other cells by their position within the vessel wall. White arrow demonstrates a PEC. Scale bar 40 μm. SMA smooth muscle area
