Abstract
Yangtze sturgeon (Acipenser dabryanus) is an endangered endemic freshwater fish of China. Cell-line is a potential means used for long-term preservation of germplasm resources and an ideal in vitro model in place of living organisms for biological studies. Here, culture condition and characterization of fin-derived cell in Yangtze sturgeon were carried out. Tissue explant techniques have been efficiently used in the Yangtze sturgeon caudal fin (YSCF) culture. The YSCF cell line showed a fibroblast-like morphology and stable growth in minimum essential medium eagle's (MEME) supplemented with 10-20% fetal bovine serum at 25°C. Cells were cryopreserved with preservative DMSO in liquid nitrogen and grew normally after recovery. No bacterial, fungal, or mycoplasma contamination was detected in the YSCF cells. Karyotype analysis of the YSCF cells showed that the chromosome numbers of the YSCF ranged from 242 to 273, and the modal chromosome number was identified as 264 at passage 9. The YSCF cells were confirmed from A. dabryanus by assay of 16S rRNA and COI. Furthermore, GFP reporter gene was successfully transferred into YSCF cells and expressed. The established YSCF cell lines will contribute to the preservation of germplasm resources and provide a useful vitro tool for further biological studies in sturgeon species.

Lee JH, Lee ST, Nam YK, Gong SP. Gene delivery into Siberian sturgeon cell lines by commercial transfection reagents. In Vitro Cell Dev Biol Anim 2019; 55:76-81. [PMID: 30644030 DOI: 10.1007/s11626-018-00316-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2018] [Accepted: 12/19/2018] [Indexed: 01/24/2023]
Abstract
The optimal transfection conditions for efficient transgene delivery into a specific cell type should be empirically determined, particularly in cases involving unusual cell types. We compared the conditions for effective introduction of transgenes into Siberian sturgeon (Acipenser baerii) cell lines by evaluating the cytotoxicity and transfection efficiency of three commercially available transfection reagents: Lipofectamine 2000, X-tremeGENE HP DNA Transfection Reagent, and GeneJuice Transfection Reagent. Plasmid vectors containing the gene encoding enhanced green fluorescent protein were mixed with each of the transfection reagents using reagent-to-plasmid ratios of 1:1, 2:1, and 4:1. Then, the complexes were used to transfect three Siberian sturgeon cell lines derived from the heart, head kidney, and gonad. Cytotoxicity and transfection efficiency were measured via flow cytometry after propidium iodide staining. No significant cytotoxicity was observed at the optimal treatment conditions in all cases, with the exception of Lipofectamine 2000-treated gonad-derived cells. Although the transfection efficiencies in A. baerii cells were generally low, X-tremeGENE HP DNA Transfection Reagent showed the highest transfection efficiency at ratios of 2:1 or 4:1, depending on the cell type. Hence, X-tremeGENE HP DNA Transfection Reagent can be used to effectively transfer foreign genes into three A. baerii cell lines.

Abstract
Cell culture is an excellent alternative for the maintenance of cell lines and to obtain quality chromosome preparations of fishes. However, this methodology is still little employed, mainly because of the difficulty of standardization of cell cultures. In this study, we describe a methodology for the rapid acquisition of cell lineages and mitotic chromosomes for cytogenetic studies of fish species from muscle tissue cells. Our methodology is based on the use of a gelatin film, which provides better adhesion of a large number of cells and appropriate conditions for multiplication. The cells of Astyanax altiparanae, used as an experimental model, with fibroblast-like morphology, showed rapid cellular proliferation, resulting in a great number of cells. Chromosomal preparations of cultured cells showed the diploid number of the species, 2n = 50 chromosomes, in 80% of the cells examined, with chromosomes intact and distended. Cell populations were cryopreserved and after being recovered, these cells maintained their proliferative capacity. The development of this methodology represents an innovation for the fish cytogenetics area and it may bring a significant contribution to the conservation and study of several groups due to the difficulty of obtaining good-quality chromosome preparations.
