Measuring miR-302b in the culture supernatant allows the detection of iPSCs in a large number of cells. (a) 107 HCT116 cells were spiked with iPSCs, and miR-302b was measured in the culture supernatant. (b) 107 HCT116 cells were spiked with iPSCs and miR-302b was measured in the cells. PC: positive control, which is the culture condition of only 106 iPS cells. UD: no miRNA detected. Error bar =  + 3SD.
