Fig. 6From: Human skin dermis-derived fibroblasts are a kind of functional mesenchymal stromal cells: judgements from surface markers, biological characteristics, to therapeutic efficacyMetabolomic analysis of UC-MSCs and HFFs. A PCA analysis of cell lysates. B PCA analysis of supernatant. C Heat maps of normalized metabolite concentrations in cell lysates. Columns represented the samples, and rows represented the metabolites. D Heat maps of normalized metabolite concentrations in supernatant. E A volcano plot based on the metabolomic data of UC-MSCs and HFFs. F A volcano plot based on the metabolomic data in supernatant. G Pie charts of differential metabolites between UC-MSCs and HFFs. H Pie charts of differential metabolites in supernatant. I Metabolic pathway analysis between UC-MSCs and HFFs. J Metabolic pathway analysis of supernatant. (Differential metabolites: p < 0.05 and fold change > 2.0 or < 0.5)Back to article page
