在当今的医学生物学研究中广泛应用离体培养的哺乳类动物细胞作为实验材料。为此,我们选择了一种与中国仓鼠同科同属,而且在染色体数目和形态方面都颇为相似的一种野生动物——灰仓鼠(Cricetulus migratorius)来建立能够长期培养的细胞系,经实验后一支由雄性成鼠腹膜建立的成纤维细胞系(命名为GH12A)获得成功。本文报告该细胞系的建立过程及对部分生物 Ex vivo cultured mammalian cells are widely used as experimental materials in current medical biology research. To this end, we selected a species of the same family of Chinese hamster, but also in the chromosome number and morphology are quite similar to a kind of wildlife - gray hamster (Cricetulus migratorius) to establish long-term culture of cell lines, the experiment The latter fibroblast cell line, designated GH12A, established by the male adult rat peritoneum was successful. This article reports on the establishment of this cell line and on some organisms
