Figure 3From: Erythropoietin-producing tubercle granuloma in a hemodialysis patient Epo expression in tubercle granuloma. In situ RNA hybridization of the resected axillary lymph node (A) and immunohistochemistry for CD68 (B), CD20 (C), and CD8 (D). (A) In situ hybridization revealing the expression of Epo mRNA in non-epithelioid cells in lymph nodes. Methods are described in the Additional file 1. Positive signals were observed in the granuloma (arrow) (×200). (B) CD68-positive cells were observed in the granuloma (arrow) (×200). (C, D) CD20- and CD8-positive cells were rarely observed in the granuloma (arrow) (×200).Back to article page
