Side population cells isolated from KATO III human gastric cancer cell line have cancer stem cell-like characteristics

Figure 4 Glyceraldehyde-3-phosphate dehydrogenase, adenosine-triphosphate-binding cassette sub-family G member 2, multidrug resistance protein 1, B-cell-specific Moloney murine leukemia virus insertion site 1 and octamer-binding transcription factor 4 RNA expression of side population and non-side population cells isolated from KATO III by reverse transcription polymerase chain reaction. SP: Side population; NSP: Non-side population; GAPDH: Glyceraldehyde-3-phosphate dehydrogenase; ABCG2: Adenosine-triphosphate-binding cassette sub-family G member 2; MDR1: Multidrug resistance protein 1; Bmi-1: B-cell-specific Moloney murine leukemia virus insertion site 1; Oct-4: Octamer-binding transcription factor 4.
