| Research Abstract |
To evaluate heterogeneity among cells in glioma tissues, we performed immunohistochemistry against mutant isocitrate dehydrogenase 1, a marker for a representative gene alteration in gliomas, together with other glioma markers (MAP-2e, p53, DCX, nestin), a proliferation marker (Ki-67) and lineage-specific markers (GFAP, Olig2, Iba-1). The results suggest existence of different tumor cell components with different genetic backgrounds and/or reactive components with a similar biological behavior to tumor cells even in one same tumor tissue. The findings would lead to the identification of tumor initiating cells, potentially a genuine therapeutic target, in tissue sections.
