Fig. 5From: Assessment of nanomaterial-induced hepatotoxicity using a 3D human primary multi-cellular microtissue exposed repeatedly over 21 days - the suitability of the in vitro system as an in vivo surrogateThe surface visualisation of MT treated with fluorescently linked polymer microspheres at 24 h. The scale bar corresponds to 200 μm and in the fluorescent images, orange colour indicates presence of fluorescent polymer microspheres and blue is an effect of autofluorescenceBack to article page
