Mass spectrometry analysis of the conditioned medium for BM-, AT-, and SM-MSCs. (a) Workflow of the preparation of conditioned medium for LC-MS/MS. (b) Venn diagram of commonly secreted proteins by three donors for each MSC type. A total of 105 and 93 proteins were commonly secreted by BM-, AT-, and SM-MSCs (all-MSCs) under normal and inflammatory conditions, respectively.
