CXCL13 Promotes the Effect of Bone Marrow Mesenchymal Stem Cells (MSCs) on Tendon-Bone Healing in Rats and in C3HIOT1/2 Cells

Objectives: Mesenchymal stem cells (MSCs) are potential effective therapy for tissue repair and bone regeneration. In present study, the effects of CXC chemokine ligand-13 (CXCL13) were evaluated on tendon-bone healing of rats. Methods: Tendon bone healing of the rat model was established and biomec...

description Objectives: Mesenchymal stem cells (MSCs) are potential effective therapy for tissue repair and bone regeneration. In present study, the effects of CXC chemokine ligand-13 (CXCL13) were evaluated on tendon-bone healing of rats. Methods: Tendon bone healing of the rat model was established and biomechanical testing was performed at 2, 4, 8 weeks after surgery. Murine mesenchymal cell line (C3HIOT1/2 cells) was cultured. The expression of miRNA-23a was detected by real-time PCR. The protein expression of ERK1/2, JNK and p38 was detected by western blotting. MiR-23a mimic and inhibitor were used to overexpress or silence the expression of miR-23a. Results: MSCs significantly elevated the levels of ultimate load to failure, stiffness and stress in specimens of rats, the effects of which were enhanced by CXCL13. The expression of miR-23a was down-regulated and the protein of ERK1/2 level was up-regulated by CXCL13 treatment in both in vivo and in vitro experiments. ERK1/2 expression was elevated by overexpression of miR-23a and reduced by miR-23a inhibitor. Conclusions: These findings revealed that CXCL13 promoted the tendon-bone healing in rats with MSCs treatment, and implied that the activation of ERK1/2 via miR-23a was involved in the process of MSCs treated bone regeneration.
