Podocyte injury resulting from VEGFR-2 inhibition in vivo. Reprinted with permission from Advani et al. (29), copyright (2007) National Academy of Sciences, U.S.A. Transmission electron micrographs of representative podocytes from vehicle-treated animals. Sprague-Dawley (SD) rat (A), spontaneously hypertensive rat (SHR) (B), and transgenic TGR(mRen-2)27 rat (C). After VEGFR-2 inhibition with the small molecule vandetanib, SD rat (D), SHR (E), and TGR(mRen-2)27 rat (F). Among vandetanib-treated groups, SD rats had occasional podocyte pseudocysts (*); SHRs showed a predominance of proteinaceous adsorption droplets (arrow), with occasional foot process fusion (arrowhead); and TGR(mRen-2)27 rats demonstrated severe podocyte injury with abundant adsorption droplet accumulation and some foot process fusion (arrowhead).
