Analysis of proliferative activity demonstrated that co-culture of SH-SY5Y with hADSCs-IL2 caused a significant decrease (~20%) in cell proliferation (cumulative proliferation index of all cell populations in co-culture, 78.1 ± 7.9%) compared to the co-culture of tumor cells with native hADSCs (100.0 ± 3.3%) or hADSCs-BFP (107.7 ± 6.6%) (n = 6, p < 0.0001) (Figure 8a). This evidence concerns the gene IL2 and neoplasm.
