DMD and infection: To this end, we started by transducing myoblasts from a donor with the DMD Δ48-50 genotype (DMD.1 myoblasts) stably expressing dgRNAΔ51 (DMD.1.dgRNAΔ51 myoblasts) with AdVP.SaC9::SpC9 or with AdVP.SaC9 and AdVP.SpC9, at total multiplicities of infection (MOIs) of 25, 50, and 100 genome copies per cell (GCs cell−1) (Figure 2A, bottom panel).
