Figure 2From: Specific-mutational patterns of p53 gene in bladder transitional cell carcinoma among a group of Iraqi patients exposed to war environmental hazardsImmunohistochemical detection of p53 nuclear reactivity in transitional cell carcinoma (a) Invasive transitional cell carcinoma, poorly differentiated (Grade III) showing no detectible nuclear p53 immunostaining (Score (−), (10X)). (b) Papillary transitional cell carcinoma, well differentiated (Grade I) showing a few p53 immunoreactivty of tumor nuclei (Score (+/−), arrowed, (10X and 40X)). (c) Invasive transitional cell carcinoma, poorly differentiated (Grade II) showing heterogeneous p53 nuclear immunostaining (Score (+); arrowed,(40X)). (d) Papillary transitional cell carcinoma, well differentiated (Grade I) showing homogenous intense p53 nuclear immunostaining (Score (++); yellow arrow, (10X and 40X), (Red arrow indicates surrounding stromal and infiltrative lymphocytes with no detectible nuclear p53 immunostaining)).Back to article page
