Fig. 4. Embryonic development of M. globulus. Embryonic development of M. globulus. Embryos observed by light (C,I–N) or SEM (B,D–H). (A) Schematic diagrams of a morula (upper) and blastula (bottom), lateral view. The area inside the black boxes was examined by SEM. (B) The internal surface structure at the vegetal pole at 3.5 h after fertilization. Each blastomere adjoined closely. (C–E) Early blastulae 4.5 h after fertilization. Cells at the lateral region with intricate elongated pseudopod-like structures (D). Some specimens had granular structures on the surface of the blastular wall (E, higher magnification of area inside white box in the insert). (F) The internal surface at the lateral region of an embryo 6 h after fertilization. (G,H) The internal surface at the vegetal plate of early mesenchyme blastulae 10 h (G) or 11 h (H) after fertilization. In the area enclosed by the dashed white circle are orbicular cells that have started to ingress into the blastocoel as PMCs (H). (I) A mesenchyme blastula 12 h after fertilization (lateral view). (J–N) Gastrulae 14 h (J), 15 h (K), 16 h (L), 17 h (M) or 21 h (N) after fertilization (dorso-ventral views). The invaginating vegetal plate is shaped like a hemisphere (J). When the archenteron had invaginated by approximately one fifth of the total length of the embryo (L), the tip of archenteron was flat and released SMCs. Some SMCs formed filopodia (black arrows) and moved in the blastocoel (K–M). Without attachment of the archenteron to the apical plate, the invagination finished (N). Scale bars: 20 μm in B,D–G; 50 μm in C,H–M. Chisato Kitazawa et al. Biology Open 2016;5:1555-1566 © 2016. Published by The Company of Biologists Ltd
