Proteomic Analysis of dental pulp stem cell-derived exosomes

In order to examine the proteomics of exosomes derived from DPSCs under hypoxia (Hypo-Exos) and the mechanism underlying the angiogenic effect of DPSC-Exos, iTRAQ-based proteomics analysis and bioinformatic analysis were performed to investigate proteome profile differences between exosomes derived from DPSCs under normoxia (Nor-Exos) and Hypo-Exos.7114 peptides and 1792 proteins were identified from the Hypo-Exos samples with a 1% FDR. Compared with the control group, 39 proteins were upregulated and 40 proteins were downregulated in Hypo-Exos.
