In vitro cytotoxicity (2A), light microscopic (2Bi), propidium iodide (2Bii), and JC-1 staining (2Biii) florescence microscopic image analysis of vehicle control, BSE, CSE, and BSE-SLNp treated human mesenchymal stem cells after 48 h. Each value is means ± SD (n = 6). *p ≤ 0.05 by comparison with vehicle control. In PI staining, the nucleus appeared to be normal and there are no signs of shrunken, pyknosis, or apoptotic nucleus. JC-1 fluorescence images showing merged images of the red and green signals of the dye, corresponding to JC-1 in J-aggregates vs. monomeric form. We found less J-aggregates and hypertrophic adipocyte in control cells. In BSE-SLNp treated adipocyte showing high J-aggregates directly representing (high MMP, Δψm) active mitochondria compared to BSE or CSE.
