HMSCs in ECM scaffold: von Willebrand factor (VWF) immunohistochemistry. The micrographs are representative images of VWF stained explant sections containing HMSCs (A,B) in control and pulp ECM scaffolds. In all the images, 1 and 2 nomenclature indicates micrographs that show expression of VWF in the periphery (1) and within (2) the respective scaffolds. The arrows in the images point to positively stained endothelial cells (black arrows) and capillary networks (white arrows). Note the absence of positive staining in the interior of the control scaffolds containing HMSCs (A2), and positive staining in the periphery of the control scaffolds (A1). Also note the presence of capillary networks in the pulp ECM scaffolds. The scale bar in all the images represents 20 μm.
