Abstract
Viral vectors represent a tractable system that can efficiently introduce an exogenous gene into different target cells and are thus a potentially powerful genetic manipulation tool. In our current study, we investigated the infection efficiency of mammalian virus vectors, adenoviruses (Ads), adeno-associated viruses, and lentiviruses to the Sertoli cell line and the newly established cell line from a single embryo in zebrafish. Among the viral vectors tested, Ads showed the highest infection efficiency of 10(7)-10(8) green fluorescent protein-transducing units (gtu)/mL in zebrafish cells. In addition, the adenoviral vector was also infected at 10(5) gtu/mL in the medaka testicular somatic cell line that was established from the testes of p53-deficient mutant. Further, we found that Ads could successfully infect cultured male zebrafish germ cells. Our results thus indicate that the adenoviral vector could be used as a chromosomally nonintegrating vector system in zebrafish.
