qPCR analysis of Krt14, Krt18 and Esr1 expression in mammary epithelial subpopulations. The data describes qPCR analysis of expression of Krt14, Krt18 and Esr1 in triplicate independent samples of CD24^+/Low Sca-1^- cells, CD24^+/High Sca-1^- cells and CD24^+/High Sca-1⁺ cells. Each data point is the mean level of expression, ± 95% confidence intervals, across the three samples of that population relative to the comparator sample. A 'round robin' comparison was used as described in the Methods. Genes considered to be characteristic of the comparator population are indicated next to each pair of graphs. Krt14 expression was undetectable in the CD24^+/High Sca-1^- and CD24^+/High Sca-1⁺ cells. Krt18 expression was undetectable in the CD24^+/Low Sca-1^- cells.
