This present invention relates to a modified mammalian cell in which the genome of the cell is modified to comprise a sequence encoding CP77 under the control of a promoter such that the modified cell line sustains propagation of a poxvirus that is less able or unable to propagate in the unmodified cell.
本发明涉及一种改造过的哺乳动物细胞,在这种细胞中,细胞的
基因组经过改造,包含一个在启动子控制下编码 CP77 的序列,从而使改造过的
细胞系能够维持痘病毒的繁殖,而这种痘病毒在未经改造的细胞中繁殖能力较弱或无法繁殖。
