The effects of VB-Ni in recipient K562 cells. (A) K562 cells were treated with or without VB-Ni, VB for 48 h or 72 h, and then observed under microscopy. (a) Microscopy image of normal K562 cells. (b) K562 cells were treated with VB for 48 h. (c) K562 cells were treated with VB-Ni for 48 h. (d) K562 cells were treated with VB-Ni for 72 h. (scale bar = 100 nm). (B) MTT measurement of cellular survival in K562 cells treated with VB or VB-Ni.
