Transfection of the human hepatocellular carcinoma cell line HuH7 with a plasmid containing a tandem copy of the duck hepatitis B virus DNA sequence resulted in transient replication of the virus. Viral particles secreted by transfected HuH7 cells exhibited physical properties similar to those of serum-derived duck hepatitis B virus and were infectious in primary duck hepatocyte cultures.
用人肝癌细胞系HuH7转染含有串联拷贝鸭乙型肝炎病毒DNA序列的质粒,导致病毒短暂复制。转染的HuH7细胞分泌的病毒颗粒表现出与血清来源的鸭乙型肝炎病毒相似的物理特性,并且在原代鸭肝细胞培养物中具有感染性。
