On the cover: Hemangioma endothelial cells co-label with markers of myeloid cells. Circular insets: Proliferative hemangioma sections were labeled with anti-von Willebrand factor to identify endothelial cells (red; bottom) and an antibody against the dendritic cell marker CD83 (green; middle). Significant, although incomplete, colocalization was observed between CD83 and the endothelium (top; merge). Nuclei were stained with DAPI (blue). (See page 621).
