A. Representative photomicrographs illustrating double immunofluorescence localization of ErbB2 (red staining) and SSTR1-5 (green staining) in MCF-7 cells (for details see legend to Figure 2). Scale bar = 25 μm. B. Quantitative analysis of MCF-7 cells showing colocalization of ErbB2 with SSTR1-5 (for details see legend to Figure 2). C. Quantitative analysis of cells showing ErbB2 and SSTR1-5 in distinct locations within the same cell. Data were analyzed as described in Figure 2.
