Angiogenic Potential of Human Neonatal Foreskin Stromal Cells in the Chick Embryo Chorioallantoic Membrane Model

Figure 4

Immunohistochemical staining of CAM alone and CAM grafted with hNSSCs for endothelial-related markers. CAMs transplanted with undifferentiated and differentiated hNSSCs (10 days) were processed and stained using the indicated antibody. Brown colour indicates areas with positive staining for the respective cell marker (smooth muscle actin (SMA), factor XIIIa, CD31, and von Willebrand factor (vWF)). The human leukocyte antigen (HLA-ABC) was used to differentiate the engraftment of human cells from chick cells (Bar = 100 μm).
