Venn diagram comparisons of lung-resident mesenchymal stromal cells (lr-MSC) and bone marrow-derived mesenchymal stromal cells (BM-MSC) highlighting their reported similarities and differences. Proteins or genes that are exclusively found on one cell population are listed in the appropriate circle. *Statistically significant difference in expression between shared proteins, with the protein listed within the circle of the cell type with higher expression. The bolded terms represent protein criteria for mesenchymal stromal cell classification. A: surface protein differences. B: transcriptome differences within cells. C: secretome differences within conditioned cell culture media. D: proteome differences within cells (10, 41, 55, 78, 91, 124, 125, 133, 144, 148).
