Fig. 6From: The expression of embryonic globin mRNA in a severely anemic mouse model induced by treatment with nitrogen-containing bisphosphonateExtramedullary erythropoiesis in newly identified structures. a Macroscopic observation of the abdominal cavity. Wine-colored structures were observed in the omentum in splenectomized mice that were treated with both NBP and PHZ (arrow). b The histological analysis stained with H-E. Numerous hematopoietic cells including megakaryocytes (arrow), were observed in these structures. c Immunohistochemical detection of TER119-positive cells. Most of the cells in this structure were TER119-positive erythroblasts. d RT-PCR analysis to determine globin mRNA levels in these newly identified structures. Both adult and embryonic globin mRNAs were expressed. Bars show 25 μm (b, c)Back to article page
