Fig. 4. The position along the DM (T2) of dorsal epithelial somite cells (T0) labeled at distinct mediolateral positions with CM-DiI. (A,C,E) Dorsal view of whole segments labeled at T0 with CM-DiI. Labeling was directed to medial, central or lateral positions of the dorsal somites, respectively. (B,D,F) At T2, the corresponding embryos were sacrificed, serially sectioned and analysed. Representative sections are shown for each type of labeling. Note that the relative mediolateral position of labeled cells at T2 was equivalent to that at T0. NT, neural tube. Scale bar: 25 µm in B,D,F.
