ABSTRACT
BACKGROUND:
Studies have shown that human placenta-derived mesenchymal stem cells with strong proliferative ability have rich sources and can remarkably promote tendon-bone healing after celltransplantation.OBJECTIVE:
To observe the effect of human placenta-derived mesenchymal stem cells on tendon-bone healing in a bone tunnel.METHODS:
Human placenta-derived mesenchymal stem cells were separated using adherent separation screening method. Thirty 8-week-old male Sprague-Dawley rats were randomly divided into two groups, 15 rats as experimental group and 15 rats as control group. Experimental group were subjected to transplantation of human placenta-derived mesenchymal stem cells and the control group were injected with saline solution. RESULTS ANDCONCLUSION:
Stem cells, new vessels, and fibrocartilage hyperplasia were observed on the tendon-bone interface with microscope at 2, 4 and 6 weeks after celltransplantation in the experimental group. Biomechanical y, the maximum pul out load in the experimental group was significantly higher than that in the control group at 4 and 6 weeks after celltransplantation (P<0.05). These findings suggest that human placenta-derived mesenchymal stem cells can accelerate early tendon-bone healing in a bone tunnel and strengthen the biomechanical strength.
