Primarily cultured cells grew well at 22℃ in Dulbecco's modified Eagle medium/F12 medium(DMEM/F12, 1:1; p H 7.2) supplemented with 20% fetal bovine serum(FBS), carboxymethyl chitooligosaccharide, basic fibroblast growth factor(b FGF) and insulin-like growth factor-I(IGF-I). The primary BFO cells in fibroblastic morphology proliferated into a confluent monolayer about 2 weeks later, and were able to be subcultured. Impacts of medium and temperature on the growth of the cells were examined. The optimum growth was found in DMEM/F12 with 20% FBS and at 22℃. The BFO cells can be continuously subcultured to Passage 120 steadily with a population doubling time of 32.7 h at Passage 60. Chromosome analysis revealed that 72% of BFO cells at Passage 60 maintained the normal diploid chromosome number(46) with a normal karyotype of 2st+44t. The results of gene transformation indicated that green fluorescence protein(GFP) positively expressed in these cells after being transformed with pc DNA3.1-GFP. Therefore, a continuous and transformable BFO cell line was successfully established, which may serve as a useful tool for cytotechnological manipulation and transgenic modification of this fish. 关键词：barfin FLOUNDER OVARY CELL CELL line gene transformation green fluorescence protein GFP Verasper moseri
