Graphic abstract

Induced pluripotent stem (iPS) cells provide a powerful platform for the study of development, regeneration, and disease. Although many stable iPS cell lines have been established for mammals, few attempts have been made to induce iPS cells in nonmammalian species. Because of technical advantages over other vertebrates on stem cells, induced pluripotent stem cells from fish could be of value for research. In this paper, stable iPS-like cell lines were generated from adult zebra fish fibroblasts by combining the doxycycline inducible lentiviral delivery system and chemical treatment. RT-PCR analysis, alkaline phosphatase staining, and immunofluorescence indicated that adult zebra fish fibroblasts were successfully reprogrammed into iPS-like cells (ziPSCs). The ziPSCs exhibited stable growth and manifested many features of fish embryonic stem cells with pluripotency in vitro and in vivo. Because of easy maintenance, the developed technology in this study for generating zebra fish iPS-like cells could be extended to investigating other genera of fish.
