Caption

(A-C) Different views to the same 7.5 day p.c. embryo. (A) Lateral view, the embryo is oriented, anterior to the left. The whole-mount picture is focused to a midsagittal plane of the embryo, revealing the ectodermal and mesodermal cell layer. (B) Posterior view, the tip of the egg-cylinder is down. The embryo proper is slightly visible by the weak brown contrast to the background. The structure of the allantois and the lateral sides of the embryo are out of plane, while the picture is focused on the posterior outline of the embryo. (C) Top view, anterior of the embryo is left. The whole-mount picture is focused on a transverse plane of the upper third of the embryo. (D,E) Different views of a 7.75 day p.c. embryo. (D) Lateral view, anterior of the embryo is left. The picture is focused on a midsagittal plane, visualizing the ectodermal cells of the headfolds and the head mesoderm. (E) Posterior view, the ventral side of the embryo is down. (A-E) Same magnification: bar, 5um. (F) Dorsal view on a 8.25 p.c. embryo, anterior to the left. The picture shows the head region with the neural folds slightly visible in contrast to the background. (G) Lateral view of a 8.5 day p.c. embryo, anterior to the left. The whole-mount picture shows the head region with the neural folds and the foregut region. The well-developed somites (6 to 7) are visible and the clear separation of segmental and lateral plate mesoderm becomes obvious. (H,I) Ventral view of a 8.75 day p.c. embryo, anterior to the left. The whole-mount is focused on the neural tube and somite level in the anterior part of the embryo. Due to the turning process, the plane passes through the closed neural tube and the adjacent somites in the middle and is in focus again at the posterior end of the embryo. (F,H) Same magnification, bar, 10 um. (I) Higher magnification of the middle portion of this embryo, demonstrating the posterior hindbrain region with the disaggregating first somites. Bar, 5 um. al, allantois; am, amnion; ec, ectoderm; fg, foregut region; hb, hindbrain; hf, headfold; lpm, lateral plate mesoderm; m, mesoderm; nec, neuroectoderm; nt, neural tube; p, primitive streak; so, somite; spm, segmental plate mesoderm; ve, visceral endoderm.
