Fig. 7. Distribution of E-cadherin in the embryo during early development. Embryos were immunostained with mAb 10H3
embedded in glycolmethacrylate and sectioned. A schematic drawing (A) indicates the cell layers seen in the sagittal section of
an embryo at stage 12.5 (B). The arrow in A indicates the original animal pole region. C represents a magnification of the
original animal pole region in B. (D) A schematic drawing indicates the cell layers seen in the transverse section of an embryo
stage 14 (E). (F) Transverse section of an embryo stage 20. np, neural plate; pe, presumptive epidermis; bl, blastocoel; ae,
archenteron, dbl, dorsal blastopore lip; vbl, ventral blastopore lip; be, bottle cells; no, notochord; pm, paraxial mesoderm; ar,
archenteron roof; nt, neural tube;. Bars represent in B and E 200/an, in C and F 50um. |
