Fig. 5From: Harmonised culture procedures minimise but do not eliminate mesenchymal stromal cell donor and tissue variability in a decentralised multicentre manufacturing approachIn vitro immunomodulatory capacities of MSCs. a PBMC proliferation after five days co-culture with MSCs under PHA stimulation. All values were normalised to PHA-stimulated monoculture PBMCs. b Mean fluorescence intensity of intracellular IDO of MSCs after being treated with IFN-γ for 24 h. c The percentage of cells positive for IDO intracellular staining. Data are displayed as mean ± SD from N = 3, n = 3. Two-way ANOVA with Tukey’s multiple comparison corrections, *p < 0.05Back to article page
