Abstract
A new cell line (TSHC) derived from heart tissues was established from female half-smooth tongue sole (Cynoglossus semilaevis), an economically important marine fish species in China. The cell line had been subcultured for more than 30 times over a period of 200 days. The cell line was optimally maintained at 24°C in minimum essential medium (MEM) medium containing foetal bovine serum (FBS), 2-mercaptoethanol (2-Me), sodium pyruvate, basic fibroblast growth factor (bFGF) and antibiotics. The TSHC cells were mostly composed of fibroblast-like cells. Chromosome analysis revealed that the TSHC cell line had a normal diploid karyotype with 2n = 42, containing the heterogametic W chromosome. The TSHC cell line was susceptible to infection by flounder Lymphocystis disease virus (LCDV). Although an atypical cytopathic effect and only few of virus particles in the cytoplasm was observed, it provides a research material on the cell–pathogen interaction research about the viral infection of non-host species.
