Fig. 1From: A risk stratification model based on four novel biomarkers predicts prognosis for patients with renal cell carcinomaRepresentative immunohistochemical images in samples from primary tumor tissues of patients with renal cell carcinoma. Expression level of each biomarker is defined as follows; “high-expression” represents staining intensity in tumor cells equal to or higher than that of normal proximal renal tubules; “low-expression” is define as either a negative reaction or lower positive staining than that of proximal tubules. Scale bars indicate 50 μmBack to article page
