Abstract
In vitro experiments were conducted to clarify the involvement of the epithelium-amebocyte interaction in epithelial regeneration of bivalves. The outer epithelia of the pallial mantle of the pearl oyster. Pinctada fucata martensii, were separated in cell sheets from the inner connective tissue layers by digestion with Dispase. Clumps of the separated mantle epithelia were inoculated onto the amebocyte layers prepared on the bottom of culture dishes and maintained at 20 degrees C in 5% CO2:95% air for 1 wk. Balanced salt solution with 0.03% (wt/vol) glucose was used as a culture medium. The epithelial cells adhered to the amebocyte layers within 24 h, changed their shape from cuboidal to squamous, and migrated and formed monolayer sheets within 3 d. Electron microscopy confirmed maintenance of epithelial polarity and cell to cell junction in the sheets; 6 d after the inoculation, 5-bromo-2'-deoxyuridine was added to the culture at 30 microns. After labeling for 24 h, the cultures were fixed and stained with anti 5-bromo-2'-deoxyuridine antibody. Cells with immunoreactive nuclei were clearly observed in the epithelial cell sheets, indicating active DNA synthesis in the epithelial sheets. Thus, cocultured with amebocytes, the out...Continue Reading
