Apoptosis of the CSLC triple-marker-positive cells versus the triple-marker-negative cells derived from MiaPaCa-2 cells

Cells were incubated in FBS-free sphere-forming medium for 7 days, followed by annexin V staining, and assessed by flow cytometric analysis. Means ± S.D. are shown. n = 3 independent experiments.

	Triple-marker-negative cells (n = 3)	CSLC triple-marker-positive cells (n = 3)	p value
Alive (%)	50.60 ± 1.85	59.43 ± 0.40	0.003
Early apoptotic (%)	22.47 ± 2.30	12.17 ± 0.63	0.004
Late apoptotic (%)	14.03 ± 1.35	22.50 ± 0.30	0.001
Non-apoptotic dead (%)	12.93 ± 1.86	5.91 ± 1.08	0.009
