Flow cytometric analysis of cells isolated from bone marrow, spleen, lymph nodes, and thymus of HOX11 transgenic diagnosed with lymphoma and control littermates. (A) Size comparisons of cells isolated from thymuses of control (broken line) and HOX11 transgenic mice with lymphoma (solid line). Also shown are two-color dot plots of thymocytes stained with CD4 and CD8, B220 and IgM, or IgM and IgD. (B) Two-color analyses of spleen cells stained with B220/IgM, IgM/IgD, or CD4/CD8. (C) Size comparisons of cells isolated from lymph nodes of control (broken line) and HOX11 transgenic mice with lymphoma (solid line). Also shown are two-color analyses of cells stained with either IgM and IgD or CD4 and CD8. (D) Two-color dot plots of bone marrow cells stained for expression of B220 and IgM or IgM and IgD.
