OGP46 promoted cell differentiation of HL-60, NB4, and Kasumi-1 cells. (A) Morphological pictures of HL-60, NB4, and Kasumi-1 cell lines were captured by oil immersion lens (×1000). (B,C) The expression of cell surface antigens in HL-60, NB4, and Kasumi-1 cells treated with 1, 2, or 1 μM OGP46, respectively, ATRA (1 μM), or Ara-C (1 μM) for 96 h. (B) Mean fluorescence intensity (MFI) of antigens. (C) A bar graph showing the statistical analysis of MFI (*p < 0.05 and **p < 0.01).
