Fig 1: Stem cells exposed to BPA analogs undergo upregulation of Caspase-6 activation. Representative fluorescent microscopy images of (A) rat ASCs and (B) human ASCs exposed to TMBPF, BPAF, and BPA. Exposed cells fluoresce green due to active Caspase-6 (blue indicates cell nuclei; magnification 200X, scale bar = 150 µm). Inset images show magnified cells expressing high cytoplasmic Caspase-6 activity (magnification 400X).
