The overlapping proteins of three exosome samples were involved in complex biological regulation. A Venn diagram of the shared proteins in hESC-Exos, hiPSC-Exos, and hUC-MSC-Exos. B and C GO and KEGG analyses of the shared proteins among the three exosome types. The red bar represents the -Log₁₀ (P-value) and the blue dot the proportion of candidate genes in the total pathway-related gene pool. D Crosstalk between the shared proteins in hESC-Exos, hiPSC-Exos, and hUC-MSC-Exos and regulated the signaling pathways they regulate. E Heatmap of the levels of shared proteins among the three exosome types. The significantly enriched pathways are shown on the right
