integrations	inside gene	outside gene
(NcoI+MseI)	26% (33% intron, 7% exon)	13%
(MseI)	39% (60% intron, 0% exon)	22%
total	65% (93% intron, 7% exon)	35%

Table 3: Genomic distribution of lentiviral integration sites in infected Sgcb-null cardiac progenitors. Percentages of vector integrations obtained by two different digestion protocols (NcoI+MseIand MseI) in infected cardiac progenitors landing inside or outside genes are shown. Note that LV-CMV-eGFP-miR669a2x vector preferentially integrated inside genes as expected.
