摘要: 建立了一种适于黄粉虫胚胎细胞的培养方法,为黄粉虫细胞培养及相关研究奠定基础。采用机械分散法和胰酶消化法,比较了黄粉虫胚胎细胞在Grace、IPL-41和Schneider′s昆虫培养基中培养的生长状况,筛选出适合黄粉虫胚胎细胞原代培养的方法及最适培养基,通过比较不同浓度梯度胎牛血清对细胞活力的影响,确定适合细胞生长的最适FBS浓度。结果表明,相对于IPL-41和Schneider′s培养基,Grace培养基中生长的细胞能够快速增殖且形态较好,且在添加20% FBS的Grace培养基中孵化7 d虫卵所接种的胚胎原代细胞生长最好。因此,采用机械分散法培养的黄粉虫胚胎原代细胞在含20% FBS的Grace培养基中能够较好地生长,并已传至第5代。

Abstract: We aimed to establish an applicable cultural method for embryonic cells of Tenebrio molitor and lay the foundation for culture of Tenebrio molitor and related research. After treated with mechanical dispersion and trypsin digestion, the optimal culture medium and fetal bovine serum(FBS) concentration were screened by comparing the growth status of the primary cells of the Tenebrio molitor embryonic cells cultured in Grace′s medium, IPL-41 and Schneider′s medium, respectively. The result showed that cellular morphology in Grace′s medium was better and grew rapidly compared with IPL-41 medium and Schneider′s medium. The optimal FBS concentration was 20% based on the comparison of the cell viability cultured in Grace′s medium with various concentrations of FBS with hatched 7 d eggs. Therefore, the primary cells of the Tenebrio molitor embryonic cells grow well in Grace′s medium with 20% FBS by mechanical dispersion and were passaged for the 5th generation period.
