Immunohistochemical staining on BL2B95 tumors on the CAM. A-F: Immunohistochemical staining of cryosections (8 μm) of BL2B95 tumors 7 days after inoculation on the CAM, counterstained with hematoxylin (C and F were not counterstained). Inserts in the lower right corner show negative controls. White arrows indicate blood vessels. A: CD20, B: CD19, C: CD10, D: CD5, E: TdT, F: HLA A,B,C. Scale bar = 80 μm. The tumors are positive for CD20, CD19, CD10 and HLA A,B,C, but negative for CD5 and TdT.
