Figure Caption
Fig. 4 TEM of single mural cells surrounding endothelial vessels in larvae. Transmission electron microscopy (TEM) images of transverse sections of 80 (a, c and e) and 120 (b, d and f) hpf larvae. (c and e) Higher magnification of MCs and ECs boxed in (a). MCs and ECs exhibit different morphologies, and tight junctions are evident between ECs (black arrows). (d–f) Higher magnification images of MCs and ECs boxed in (b). Both ECs and MCs exhibit a more elongated morphology at 120 than 80 hpf. L, lumen. Scale bars, 5 μm.
