Fig. 5From: Nanomicelles potentiate histone deacetylase inhibitor efficacy in vitroFig. 4 PI nanomicelles uptake by MCF-7 cells. Confocal images of MCF-7 cells were taken at 4 h, 24 h and 48 h after treatment. A negative control with unstained cells and a positive control involving the addition of Triton-X followed by PI were used. Cell nuclei are stained in blue, while PI fluorescent signal is highlighted in redBack to article page
