In this report, we show that larval flagellated cells transform into choanocytes during metamorphosis.
Flagellated cells make up the entire larval surface, except at the posterior end where many reddish brown pigment granules occur in the cytoplasm.
The larval surface region consists of a pseudostratified columnar epithelium of elongate flagellated cells; however, a basal lamina is absent [ILLUSTRATION FOR FIGURE 1 OMITTED].
Flagellated cells have the smallest nucleus (about 3.2 [[micro]meter] in length and 1.8 [[micro]meter] in width) among larval cell types.
We found minute electron-dense granules concentrated in the apical cytoplasm near the free surface of larval flagellated cells [ILLUSTRATION FOR FIGURES 1, 2 OMITTED!.
Figure 4 shows that flagellated cells are losing their characteristic morphology and the pseudostratified columnar epithelium is in the course of disorganization at the surface of such metamorphosing larva.
The coeloblastula is a hollow spheroid consisting of a layer of flagellated cells around a large central cavity (Fig.
Flagellated cells. Figure 2 shows the flagellated cells of the coeloblastula of L.
Figures 4 and 5 show magnified images of the apical region of flagellated cells. It is apparent that one flagellum emerges from the flat outer surface of the cell.
We found a consistent arrangement and orientation in the apical region of larval flagellated cells. One side of the outermost portion of the cell protrudes toward a neighbor cell, and the protrusion is regularly directed to the anterior end of the larva (Figs.
Figure 6 shows glutinous granules of about 1-[micro]m diameter in the apical cytoplasm of flagellated cells. Their surface layer is very electron-dense, and the inner part is made of the loose network of a fine granular substance.
Bottle cells are large (about 18 X 6 [micro]m) cells that are located between flagellated cells but have no flagellum themselves (Fig.
In summary, the results demonstrate that, in Microciona larvae, mannose is the only terminal, lectin-binding sugar on the surface of the flagellated cells as shown by con A staining.
We suggest that mannose receptors are present on the surface of phagocytes in the larvae (as shown in a variety of other organisms) (9) and that such receptors recognize and bind with mannose on apoptotic flagellated cells. A mannose-mannose receptor reaction may be required for ingestion of the apoptotic cells (9, 10).
Our study supports the theory that peripheral flagellated cells in Microciona larvae are terminally differentiated; their fate is apoptosis and eventually phagocytosis.
