From: The emergence of non-secretory multiple myeloma during the non-cytotoxic treatment of essential thrombocythemia: a case report

Figure 5

Expression of vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS) and hypoxia-inducible factor 1-alpha (HIF1α) was analyzed using immunohistochemistry on bone marrow biopsy specimens of essential thrombocythemia (ET) and multiple myeloma (MM) (before and after chemotherapy). VEGF expression: (a) at ET diagnosis, (b) at MM diagnosis, (c) in MM after chemotherapy. eNOS expression: (d) at ET diagnosis, (e) at MM diagnosis, (f) in MM after chemotherapy. HIF1α expression: (g) at ET diagnosis, (h) at MM diagnosis, (i) in MM after chemotherapy. Magnification x40. Immunoreactive cells are colored brown. The black arrows point toward positive cells.
