Three new continuous cell lines from marine fishes of asia

Summary Three new continuous cell lines were established from two species of marine fishes economically important in Asia. Perch (Lateolabrax japonicus) heart (PH), perch liver (PL), and grouper (Epinephelus amblycephalus) kidney (GK) lines were established in Eagle’s minimum essential medium with 10% fetal bovine serum and have been subcultured over 120 times. The optimum growth temperature was 25°C for the PK and GK lines and 30° C for the PH line. The modal chromosome numbers for each cell line are: PH (49), PK (50), and GK (65). None of the lines was susceptible to the rhabdovirus infectious hematopoietic necrosis virus (IHNV) or channel catfish herpesvirus (CCV); however, all three cell lines were susceptible to a variety of fish birnaviruses, including infectious pancreatic necrosis virus (IPNV), the EVE eel virus, and newly isolated birnaviruses from a variety of fish and shellfish in Taiwan. This research was funded by National Science Foundation grant INT-810447, the University of Main/University of New Hampshire Sea Grant College Program, and the Maine Agriculture Experiment Station publication no. 1165.
