Abstract

Replication-defective retroviral vectors are efficient vehicles for the delivery of exogenous genes, and they may be used in the generation of transgenic animals. The replication-defective retroviral SNTZ vector carrying the lacZ gene with a nuclear localized signal was injected into the subgerminal cavity of freshly laid eggs. Subsequently, the eggs were allowed to hatch, and the chickens were screened for the lacZ gene by using the polymerase chain reaction. Eight of 15 male chickens that survived to sexual maturity contained the lacZ gene in their semen. Subsequently, these males were mated with wild-type female chickens. In this study, performance of the SNTZ vector carrying theEschrichia coli lacZ gene to express a nuclear-localized β-galactosidase was injected into the subgerminal cavity of embryos collected from newly laid eggs was reviewed.

 

Key words: Transgenic chickens, lacZ, β-galactosidase and retroviral vector.
