Figure 4:

Cytokine secretion of encapsulated hMSCs in 6, 8 and 10 wt% PEG-4aNB microgels in the absence and presence of IFN-γ. A) Heat map and two-way hierarchal clustering of analyte secretion. b) Principal components analysis (PCA) for analytes secretion. c) Individual analysis of factors secreted from encapsulated hMSCs in 6, 8 and 10 wt% PEG-4aNB microgels; n = 3 biologically independent samples, mean ± SD; *p < 0.05, **p < 0.01, ***p < 0.001, ****p<0.0001. One-way ANOVA analysis was used to detect differences among samples.
