Figure 1From: Expression of fibroblast specific protein-1 in pleural tuberculosis and its clinical biological significanceThe expression of S100A4 in pleural tissue. (A) HE stained of tuberculous pleurisy (10 × 10). (B) S100A4 protein expression in tuberculous pleurisy in cell cytoplasm and nucleus, stained by S-P method (10 × 10). The S100A4 positive cells are brown. (C) HE stained of normal pleural tissue (10 × 10). (D) No brown cells were observed. S100A4 protein is not expressed in normal pleural tissues, stained by S-P method (10 × 10).Back to article page
