Exosomes from LPS-Stimulated hDPSCs Activated the Angiogenic Potential of HUVECs In Vitro

Isolation and identification of hDPSCs. (a) Primary cultured hDPSCs (scale bar, 200 μm). (b) The cell morphology of hDPSCs was observed under an optical microscope (scale bar, 200 μm). (c) Osteogenic differentiation assay of hDPSCs (scale bar, 200 μm). (d) Adipogenic differentiation assay of hDPSCs (scale bar, 50 μm). (e–i) Flow cytometry assays showed high levels of the mesenchymal stem cell markers CD90 (90.50%), CD44 (99.27%), and CD29 (99.63%) and low levels of the hematopoietic cell markers CD45 (0.16%) and CD34 (0.32%) in hDPSCs.
