Three types of clonal cell lines were isolated according to their size and phenotype from the adherent cell populations in long-term liquid cultures from the embryonic fibroblast cells of Zebrafish, Danio rerio. All kind of cell lines were well proliferated. The size and number of clonal cell lines derived colonies from stable embryonic cells were significantly increased in the presence of NAC and A2P conditioned medium from the cell lines. The stable cell lines and clonal cell lines were cap-able of well proliferation in vitro. These cell lines have been maintained in continuous culture without change in characteristics. A majority of the clonal cells (80%) was shown a normal chromosomal complement (50 chromosomes, 2N) in according with FACs analysis. Majority of cells were positive to vimentin staining and none of them were positive for nestin and Oct -4 by immunocytochemistry. These results indicate that the clonal cell lines obtained from cultured cells are fibroblasts and may be extremely useful in genetic manipulation for further nuclear transfer and fish cloning.
