hWJ-MSC CM proteomic analysis. Graphical representation of WJ-MSC CM proteomic analysis by mass spectrometry. Peaks detected (from different donors: WJ1, WJ2, WJ3) after CM analysis show that the patterns of protein expression are modulated when we change from a normoxic to b hypoxic culture conditions. Indeed, the Venn diagrams (c) indicated that more proteins were identified in the hWJ-MSC CM collected from hypoxic conditions (166 proteins) when compared to the normoxic hWJ-MSC CM (104 proteins), in which 81 were common to the two conditions. The color scale shown illustrates the relative expression of the indicated proteins across the samples: red denotes low expression and green denotes high expression
