We describe a system for introducing guide RNAs (gRNAs) to Cas9-expressing hematopoietic stem cells, which are used to generate mice with gene knockouts in the immune system. By using different gRNA-containing vectors and Cas9-expressing mice, we created systems for knockout of single genes or pairs of genes constitutively or inducibly.

USA 112, 512–517 (2015). This paper shows that direct transduction of CD8+ T cells alters their differentiation, whereas lentiviral transduction of bone marrow stem cells, which subsequently differentiate into naive CD8+ T cells containing the lentiviral vector, does not.
