| Description | Figure 5. Gastrulation of Abatus cordatus. (A) Condensed representation of gastrulation. The vestibule is differentiated only in the late gastrula. (B) Broadcast of the mesenchyme cells through the gastrular epithelium from the mesenchyme to the vitelline space at the animal pole. Inset shows an infiltrated nucleated mesenchyme cell in the gastrular epithelium. (C) Cell mass isolated in the gastrular epithelium that will give the vestibule. (D) Cross section of a 50-day-old gastrula filled with mesenchyme. (E) Local disorganization of the gastrular epithelium at the animal pole. Nucleated cells are visible in the mesenchyme. B to D are semi-thin plastic sections (toluidine blue, pH 11.5). Abbreviations: aep, archenteric epithelium; ap, animal pole; ar, archenteron; bp, blastopore; fm, fertilization membrane; gep, gastrular epithelium; mc, migrating cells; mes, mesenchyme, N, nucleus; V, vestibule; vp, vegetal pole; vs, vitelline space. Scale bar = A and D, 250 um; B, 50 um; C and E, 100 um |
