Analysis of markers of cancer stem cells and genes involved in drug resistance.

<p>A. Flow cytometry analysis for the expression of CD24 and CD44 in treated cells. B. Real time PCR analysis of expression of CD44, CD24, ABCB1, mdm2, ABCG1 and ABCG2. The data was plotted as the ratio of gene expression in treated sample to untreated sample for the respective cells. Statistical significance is denoted by * (p<0.05), ** (p<0.01) and *** (p<0.001).
