Abstract : The present study reports a culture technique for heart tissues of the<br />

European fiat oyster, Ostrea edulis. Heart tissues of fiat oysters were dissociated by<br />

a trypsin-EDTA treatment and a mechanical action in a Dounce-type homogeneizer.<br />

Then, dissociated cells were cultured in three different synthetic media, in pure sea<br />

water or in sea water mixed with sterile filtered Japanese oyster, Crassostrea gigas,<br />

hemolymph. AI! these media were supplemented with 10% of fetal bovine serum.<br />

Cultures were grown at 20· C in previously Poly-DLysin coated flasks or culture wells.<br />

The optimized medium, 3% L 15 medium (w/v) in sterile sea water mixed with<br />

Japanese oyster hemolymph (1 :1) and supplemented with 10% offetal bovine serum<br />

gave the best result. Morphological characterization for the cardiac cultured cells was<br />

performed. Thus, cell monolayers of dissociated heart tissues consisted essential!y of<br />

hemocytes and large granular pigmented cells.<br />

Key words : Bivalve, Cell culture, European fiat oyster (Ostrea edulis), Heart<br />
