PG - 511-8 LID - 10.1159/000257495 [doi] AB - The proangiogenic action of human adipose tissue-derived mesenchymal stem cells (hASCs) transplantation has been shown to be mediated by secretory factors. In this study, we determined if human granulocyte chemotactic protein-2(GCP2) or monocyte chemoattractant protein-1(MCP1) is involved in the proangiogenic action of hASCs transplantation in the hindlimb ischemia model. hASCs secrete GCP2 and MCP1, which leads to increased tubule formation. The downregulation of GCP2 or MCP1 decreased MCP1 and GCP2 secretion, respectively, whereas the external addition of GCP2 or MCP1 increased MCP1 and GCP2, respectively. Additionally, the treatment of GCP2 and MCP1 increased VEGF secretion, while the downregulation of GCP2 and MCP1 showed the opposite effect on VEGF secretion. Downregulation of GCP2 and MCP1 expression also inhibited hASCs-induced proangiogenic action, while the overexpression of GCP2 increased it. Finally, the downregulation of MCP1 or VEGF inhibited the GCP2 overexpression-induced increase in blood flow recovery. Taken together, these data indicate that the proangiogenic action of hASCs transplantation is mediated by the interaction between GCP2, MCP1 and VEGF, which are secreted from the transplanted cells.
