英文摘要	The skin of the amphibian Bombina maxima is rich in biologically active proteins and peptides, most of which have mammalian analogues. The physiological functions of most of the mammalian analogues are still unknown. Thus, Bombina maxima skin may be a promising model to reveal the physiological role of these proteins and peptides because of their large capacity for secretion. To investigate the physiological role of these proteins and peptides in vitro, a fibroblast cell line was successfully established from Bombina maxima tadpole skin. The cell line grew to form a monolayer with cells of a uniform shape and abundant rough endoplasmic reticulum, which are typical characteristics of fibroblasts. Further identification at a molecular level revealed that they strongly expressed the fibroblast marker protein vimentin. The chromosome number of these cells is 2n = 28, and most of them were diploid. Growth property analysis showed that they grew well for 14 passages. However, cells showed decreased proliferative ability after passage 15. Thus, we tried to immortalize the cells through the overexpression of SV40 T antigen. After selecting by G418, cells stably expressed SV40 large T antigen and showed enhanced proliferative ability and increased telomerase activity. Signal transduction analysis revealed functional p42 mitogen-activated protein (MAP) kinase in immortalized Bombina maxima dermal fibroblasts. Primary fibroblast cells and the immortalized fibroblast cells from Bombina maxima cultured in the present study can be used to investigate the physiological role of Bombina maxima skin-secreted proteins and peptides. In addition, the methods for primary cell culturing and cell immortalization will be useful for culturing and immortalizing cells from other types of amphibians
