Spatiotemporal retroviral gene transfer into specific somatic mammalian cells using the avian RCAS (replication-competent avian sarcoma-leukosis virus long terminal repeat with splice acceptor)/tumor virus A (TVA) system is a versatile tool for performing lineage tracing and gene function analysis in vivo. RCAS retroviruses carrying the subgroup A envelope transduce only genetically engineered mammalian cells that express the cognate avian retroviral receptor TVA. The RCAS/TVA gene delivery system has been successfully used in various different mouse TVA-expression models. This protocol contains a detailed description of the production of high-titer RCAS retroviruses in chicken fibroblasts and the transduction of proliferating TVA-positive somatic mammalian cells in vivo. By taking advantage of the combination of the RCAS with the 'universal' Cre/loxP system, the protocol can be used in nearly every proliferating cell type in vivo. The protocol takes 4 weeks from transfection of chicken fibroblasts, which act as the host cells for viral production, to the transduction of TVA-transgenic mice.
