Abstract

There are currently limitations in stem cell therapy due to the low rate of homing and proliferation of cells following transplantation. The present study was designed to investigate the effects of Tenascin‑C (TN‑C) on bone marrow mesenchymal stem cells (BMSCs) and its underlying mechanisms. BMSCs were obtained from C57BL/6 mice. The survival and proliferation of BMSCs was analyzed by Cell Counting Kit‑8 assay, migration was evaluated using the Transwell method, and differentiation was assessed by immunocytochemistry and immunofluorescence. In addition, the levels of proteins were detected by western blotting. High concentrations of TN‑C promoted the migration of BMSCs. H2O2 at concentrations of 60‑90 µmol/ml induced cell death in BMSCs, and thus, it was used to simulate oxidative stress in the microenvironment of acute myocardial infarction (AMI). High concentrations of TN‑C were able to protect BMSCs from cell death, and promoted the migration of BMSCs (P<0.05). However, TAK‑242 [the inhibitor of Toll‑like receptor 4, (TLR4)] reduced the promoting effect of TN‑C (P<0.05). By contrast, TN‑C had no effect on the proliferation and differentiation of BMSCs. TN‑C reduced the phosphorylation levels of p38 mitogen‑activated protein kinase (MAPK), and increased the phosphorylation levels of Ser473 protein kinase B (AKT) and β‑catenin, all of which were inhibited by TAK‑242 (P<0.05). In the simulated AMI microenvironment, TN‑C promoted the migration of BMSCs via TLR4‑mediated signaling pathways, including MAPK, AKT and Wnt.
