Pancreatic cancer stem cells surface markers expression in the side population (SP) versus the non-side population (NSP). CD44, CD24, CD326 positive and negative combinations are shown within the non-side population (NSP) and side population (SP) in various cell lines. Here we show that various combinations are statistically significantly different from each other (*, p < 0.01) in different cell lines (A–E). Comparing the previously described CD44+CD24+CD326+ cells with CD44-CD24-CD326+ cells shows that the latter is present in relatively higher amounts in the SP than in the NSP in 4 of 5 cell lines (F). The triple positive cells are lower in the SP than NSP in all cell lines. Cell surface marker combinations that are statistically higher in the SP than in the NSP are shown: CD44+/CD24−/CD 326+ is only significant in panc-1 cells; CD 44+CD24-CD326- and CD44-CD24+CD326+ are significant in 3 of 5 cell lines. CD 44-CD24-CD326+ is significant in 4 out of 5 cell lines(G).
