实验用细胞株乃两株袋鼠(Potorous tridactylis)细胞经体外培养了100多代。一株标号为RH_(16),其染色体为正常整倍体(2n=12)。另一株标号为RH_5,为失去5号染色体,形成亚倍体(2n=11)细胞。两种细胞株置于37℃、胎牛血清培养基中培养。
Experimental cell lines are two strains of Kangaroo (Potorous tridactylis) cells cultured in vitro for more than 100 generations. A strain of RH_ (16), the chromosome is normal euploid (2n = 12). Another strain is labeled RH_5, in order to lose chromosome 5, forming a diploid (2n = 11) cells. Both cell lines were cultured in fetal bovine serum medium at 37 ° C.
