CCN1 and invasive ductal breast carcinoma: Analyzing if expression was detected (immunofluorescence signal for CYR61 and/or S100A4 1-5 spots +; 5-10 spots ++; >10 spots +++) or not (–), we find the following pattern: 90.2% of invasive ductal carcinomas were positive for CYR61 expression, 82% were positive for S100A4 expression and 78% showed both CYR61 and S100A4 expression (Figure 6A and Figure S7).
