Fish cell lines: establishment and characterization of three new cell lines from grass carp (Ctenopharyngodon idella).

Three new cell lines were established from tissues of the grass carp, Ctenopharyngodon idella. Derived from the fin, snout, and swim bladder of two apparently healthy diploid fry, these cell lines have been designated GCF, GCS-2, and GCSB, respectively. The cells grew at temperatures between 24 degrees and 36 degrees C with optimal growth at 32 degrees C and have been subcultured more than 50 times since their initiation in August 1986. Two of the lines remained diploid or pseudodiploid after 38 passages. The cells were tested for microbial contamination, and plating efficiencies were determined. The three cell lines were sensitive to Rhabdovirus carpio (RVC), infectious hematopoietic necrosis virus (IHNV), golden shiner virus (GSV), chum salmon virus (CSV), and infectious pancreatic necrosis virus serotype VR299 IPNV). They were refractory to channel catfish virus (CCV), channel catfish reovirus (CRV), chinook salmon paramyxovirus (CSP), and an Ab serotype of IPNV.
