Figure 2From: Overexpression of CD44 accompanies acquired tamoxifen resistance in MCF7 cells and augments their sensitivity to the stromal factors, heregulin and hyaluronan CD44 is associated with erbB2 and erbB3 in TamR cells. Immunofluorescence microscopy of CD44 (green) revealed a largely cell-surface location. Subsequent staining of erbB2 and erbB3 (red) and image overlay revealed apparent co-localisation (yellow/orange) of these receptors in TamR cells.Back to article page
