Abstract
Chinese perch (Siniperca chuatsi), an important fish for the aquaculture industry of China, is often affected by viral diseases. A stable and sensitive cell line can play an important role in virus identification and isolation, functional gene identification, virus pathogenic mechanism and antiviral immunity study. In the present study, a new cell line (S. chuatsi skin cell, SCSC) derived from the skin of S. chuatsi was established. The SCSC mainly consisted of fibroblastic-like cells, which grew well in M199 medium supplemented with 10% foetal bovine serum at 25°C. Chromosome analysis revealed that the SCSC (44%) has a diploid chromosome number of 2n = 48. The SCSC can be transfected and expressed exogenous gene efficiently. It also showed high sensitivity to several aquatic animal viruses from different families including Rhabdoviridae, Iridoviridae and Reoviridae. In addition, RT-PCR showed that S. chuatsi rhabdovirus (SCRV) started genome replication as early as 3 h post infection in the cells, which also induced the up-regulation of a variety of immune-related genes including these related to interleukin family, pattern recognition receptors, JAK-STAT pathway and interferon regulatory factors. In summary, current study provided a new tool in research of fish viruses and its interaction with host.

Abstract
In this study, we established and characterized a continuous cell line from the spinal cord tissue of mandarin fish, Siniperca chuatsi and assessed its susceptibility to infectious spleen and kidney necrosis virus (ISKNV), Siniperca chuatsi ranavirus (SCRaV) and Siniperca chuatsi rhabdovirus (SCRV). The cell line, named SCC, has been successively cultured up to 40 passages. The optimal growing conditions of SCC cells were in Leibovitz's L-15 medium supplemented with 20% foetal bovine serum (FBS) at 28°C. Karyotype analysis demonstrated 48 normal diploid chromosomes in the cells. The identity of S. chuatsi origin of SCC cells was confirmed by partial sequencing of the 16S rRNA and cytochrome oxidase I (COI) genes. Infection susceptibility assessment showed that ISKNV, SCRIV and SCRV and can be stably produced and transmitted in SCC cells, and the replication efficiency of ISKNV, SCRaV and SCRV ranged from 107.4 to 109.6 TCID50 /ml. In addition, transmission electron microscopy analysis of ISKNV, SCRAV and SCRV infected SCC cells showed numerous viral particles. In conclusion, the newly established SCC cells provide an important tool for isolation and production of viruses, as well as for molecular and cell biology studies.
