Fig. 2From: MCM4 expression is associated with high-grade histology, tumor progression and poor prognosis in urothelial carcinomaAnalysis of MCM4 expression in the surface area and invasive front. A Low-power magnification of MCM4 in UC tissues including the surface area and invasive front. B MCM4 expression on tumor surface. C MCM4 expression in tumor invasive front. D Comparison of MCM4 expression between the surface area and invasive front in all upper tract UC tissues (n = 124). Statistical significance was determined by the Wilcoxon signed-rank test.
