PR detection in CD49f/CD24 sorted cell populations. A) dCt values obtained by subtracting 18S rRNA from gene of interest. dCt values are inversely proportional to expression. Black symbols: benign tissue samples (B), red symbols: IHC designated ER positive IDC tumor samples (+), blue symbols: IHC designated ER negative IDC tumor samples (−). B) Fold change when sorted cell values were compared to tumor of origin. C) Fold change when tumor sorted cell values were compared to averaged benign tissue values. D) Fold change when sorted cell values from tumor samples were compared to averaged sorted cell values from benign tissue. Black bars indicate median values. (*, p-value <0.05).
