Bone Marrow Mesenchymal Stem Cells (BMSC) Homing with Chemotaxis Transplantation of Stromal Cell-Derived Factor 1a Promotes the Corneal Damage Repair

This study analyzed the effect of bone marrow mesenchymal stem cells (BMSC) homing with chemotaxis transplantation of SDF-1a on the repair of corneal damage. The SDF-1a with varied concentration was added. They were divided into A group, B group, C group, D group and con-trol group followed by analysis of corneal cell survival by MTT, apoptosis by flow cytometry, and Trkb level by immunohistochemical staining. There was an increasing tendency on the quantity of chemotactic cells (P < 0.05) with a highest quantity in C group. The recruitment of BMSC could be prompted by SDF-1a and the chemotactic effect was the best when SDF-1a concentration was 100 ng/ml. The survival rate and Trkb protein level in experimental groups was higher than that in control group with highest survival rate and Trkb level in C group. In conclusion, corneal injury repair is prompted by BMSC homing with chemotaxis transplantation of SDF-1a, indicating that it might be used as a novel approach to promote corneal injury repair.

Automated summary

This study investigated the effect of chemotaxis transplantation of SDF-1a on the repair of corneal damage using bone marrow mesenchymal stem cells (BMSC). The results showed that SDF-1a could promote the recruitment of BMSC, with the best effect at a concentration of 100 ng/ml. The experimental groups had higher survival rates and Trkb protein levels compared to the control group, with the C group showing the best results. In conclusion, chemotaxis transplantation of SDF-1a with BMSC can enhance corneal injury repair.
