T cells develop in the thymus from bone marrow precursors, and genetic manipulation is an indispensable tool to explore their development in vivo. Retroviral transduction of T cell precursors in the bone marrow can be used to specifically eliminate or enforce gene expression. Here, we describe a fast and efficient method to ectopically express a gene in T cell precursors through retroviral transduction and transplant into recipient mice, which will enable laboratories to evaluate gene function in T cell development in vivo.
