(A) Cellular and supernatant NK cell regulatory miR expression of MUM2B and OCM1 cells. Data represent mean ± SD, n = 4. *, P <0.05 MUM2B vs. OCM1. (B) Cellular expression of NK cell regulatory miR by MUM2B and OCM1 cells when enriched for CD271+ and CD271− fractions by magnetic cell sorting. Data represent mean ± SD, n = 3. (C) Changes in cellular NK cell regulatory miR expression of MUM2B and OCM1 cells cultured in stem-cell supportive media for 2, 3, or 7 days compared to culture as monolayers in DMEM (Day 0). Data represent mean ± SD, n = 3. *, P <0.05 vs. Day 0.
