Figure 1.

Efficient transduction of cardiomyocyte progenitor cells (CMPCs) with lentivirus (LV) vectors. CMPCs were transduced with LV-DsRed at multiplicities of infection (MOIs) of 1, 2, and 10. Four days after transduction, cells were assessed by fluorescence microscopy (left) and flow cytometry (right). Histogram plots demonstrate that the proportion of DsRed-positive cells increases as a function of the MOI. Transduction efficiency is presented as mean ± standard error of the mean (SEM) (n = 3).
