Summary
Two cell lines were established from explants of trunk musculature of healthy, males sand seatrout,Cynoscion arenarius. One of the lines, designated CyA-1, has been carried through 150 subcultures during 6 yr. The other, designated CyA-2, has been carried through 100 subcultures during 2 yr. Both lines grow well in L15 medium adjusted to 0.150M NaCl and supplemented with 10% fetal bovine serum. Optimal growth occurs at temperatures between 24 and 30°C. The species of origin of both lines was confirmed by a cytotoxic antibody dye exclusion test. The karyotype of CyA-1 has not yet stabilized, showing a modal chromosome number of 120 at Passage 9, 89 at Passage 63, and 79 at Passage 100. The karyotype of CyA-2 is rather stable, with a modal chromosome number of 47 at Passage 1 and 49 at Passage 100. Chromosome morphology of CyA-2 is homogeneous (small, acrocentric), whereas the chromosomes of CyA-1 show considerable size variation (with small chromosomes possibly formed from fragmentation of original structures). Both lines were found to be free of bacterial or fungal contamination. Both lines supported replication of lymphocystis virus strains isolated fromBairdiella chrysura (the silver perch) and fromMicropogon undulatus (the Atlantic croaker) but were refractory to 11 other viruses (4 from fish, 1 from amphibians, and 6 from mammals).
