Summary

edit
Description Figure 7. End of gastrulation. (A) Oblique section near the blastopore of a gastrula (between 50 and 55 days old) passing through the archenteron and one coelomic cell mass (white box). (B) Detail of the coelomic cell mass (outlined in Fig. 7A). (C) Sectioned gastrula (between 60 and 65 days old) filled with mesenchyme cells. The perivitelline space is virtually absent. The embryo takes all the room; it is in direct contact with the fertilization membrane. (D) Detail of the outlined mesenchyme cells in Fig. 7C showing interphase and mitotic (metaphase) nuclei. A to D are semi-thin plastic sections (toluidine blue, pH 11.5). Abbreviations: aep, archenteric epithelium; ar, archenteron; ce, primordial coelomic epithelium; fm, fertilization membrane; gep, gastrular epithelium; Id, lipid droplet; M, mitosis; mc, migrating cells; mes, mesenchyme; N, nucleus; vs, vitelline space. Scale bar = A and B, 100 wm; C, 250 um; D, 25 um.
