Recruitment of immune cells to xenografts of U87-MG cells overexpressing either KPC1- or p50. U87-MG cells overexpressing KPC1, p50, or a control vector, were injected subcutaneously into nude mice. Tumors were harvested, processed, and stained with hematoxylin and eosin staining (H&E), or immunostained for LYVE-1, a lymphatic vessels marker. Shown are representative photomicrographs of a single tumor from each group. Arrowheads indicate infiltrated immune cells in the KPC1- and p50-expressing tumors. Arrows indicate LYVE-1 immunostaining. Scale bars, 50 μm
