Long-term immune restoration in T cell immunity and in situ transduction of BM CD34+ HSPCs. (A) Kinetics of gene marking based on fluorophore expression in PB lymphocytes from H867 treated with FV-PGK-mCherry-γC. Lymphocyte population was defined based on forward and side scatter. (B) Kinetics of CD3+ cell reconstitution (based on CD3+ cells per microliter of blood) in H867. (C) TRECs in PB of H867 (D) colony forming potential of BM CD34+ HSPCs in comparison with healthy dog 3.5 years postviral vector injection. (E) Colony forming potential of mCherry+ HSPCs, which shows transduction of stem cells by FV vector. Scatter was defined based on forward scatter (FSC) and side scatter (SSC) profile. HSPCs were defined as CD45+CD34+ cells from BM. BM, bone marrow; FSC, forward scatter; FV, foamy viral; FV-PGK-mCherry-γC, FV expressing mCherry and γC under human phosphoglycerate kinase promoter; HSPC, hematopoietic stem and progenitor cell; PB, peripheral blood; SSC, side scatter; TREC, T cell receptor excision circle.
