Fig. 2From: Comparison of hybrid clones derived from human breast epithelial cells and three different cancer cell lines regarding in vitro cancer stem/ initiating cell propertiesParental cells and hybrid cells exhibit a unique population of ALDH positive cells. Two M13SV1-EGFP-Neo controls are shown here because M13HS and M13MDA435 hybrid clones and M13MDA231 hybrid clones were independently analyzed from each other. Shown are the means ± STD percentage of ALDH positive cells (ALDH data minus control data) of at least three independent experiments. Representative FACS data are presented in Supplementary Figure 1Back to article page
