Fig. 4From: Microbial antigens-loaded myeloma cells enhance Th2 cell proliferation and myeloma clonogenicity via Th2–myeloma cell interactionTumor colony appearance. The clonogenicity assays were performed in methylcellulose. Treated tumor cells were plated with MM-Th2 cells (Tumor + Th2), without MM-Th2 cells (tumor Alone), with MM-Th2 cells and anti-HLA-DR (Anti-HLA-DR), or with MM-Th2 cells and control IgG2b (control IgG2b). Micrographs represent the appearance of colonies at low power. (Upper panel) Appearance of colonies of treated-RPMI8266 cells (tumor cells: 10,000/well). (Lower panel) Appearance of colonies of primary myeloma cells from bone marrow (tumor cells: 100,000/well). Arrow: pointing to tumor colonyBack to article page
