Fetal vs adult mesenchymal stem cells achieve greater gene expression, but less osteoinduction

Figure 5 Mesenchymal stem cells viability and proliferation post-transduction. A: Mean ± SD percent of viable cells as determined by 7-AAD positivity in flow cytometry at the indicated days post-transduction with Ad-GFP; B: Cumulative relative number of cells of Ad-GFP-MSCs and control MSCs. An estimated cell proliferation rate of 45 h and 29 h for aMSC or fMSCs, respectively, was determined from the slope of the curves; not significantly different between treated and control cells. Ad-GFP: E1-A-deleted-green fluorescent protein; fMSCs: Fetal mesenchymal stem cells; aMSCs: Adult mesenchymal stem cells.
