[Influence of TLR2 and TLR4 agonists on migration of human bone marrow mesenchymal stem cells].

This study was aimed to investigate the influence of TLR2 and TLR4 agonists on the migration and adhesion activity of human bone marrow-derived mesenchymal stem cells (MSC) and to clarify the underlying mechanisms. The expression of TLR2 and TLR4 on MSC was detected by flow cytometry. The effects of TLR2 agonist (PAM3CSK4) and TLR2 agonist (LPS) on MSC migration and adhesion ability were evaluated with chemotaxis and adhesion test.
