- A new cell line (TSHKC) derived from half-smooth tongue sole (Cynoglossus semilaevis) head kidney was developed. The cell line was subcultured for 40 passages over a period of 360 days. The cell line was optimally maintained in minimum essential medium supplemented with HEPES, antibiotics, fetal bovine serum, 2-Mercaptoethanol (2-Me), sodium pyruvate and basic fibroblast growth factor. The suitable growth temperature for TSHKC cells was 24 °C, and microscopically, TSHKC cells were composed of fibroblast-like cells. Chromosome analysis revealed that the TSHKC cell line had a normal diploid karyotype with 2n = 42, contained the heterogametic W chromosome. The TSHKC cell line was found to be susceptible to lymphocystis disease virus. The fluorescent signals were observed in TSHKC when the cells were transfected with green fluorescent protein and red fluorescent protein reporter plasmids.
