Abstract:

BACKGROUND: Numerous studies have demonstrated that estrogen can regulate the proliferation and migration of endothelial progenitor cells (EPCs), while EPCs can also promote the function and activity of bone marrow mesenchymal stem cells (BMSCs) in vitro.
OBJECTIVE: To evaluate the ability of the BMSCs and EPCs which construct the composite cell sheet in the repair of alveolar bone defect in ovariectomized rats.
METHODS: BMSCs/EPCs composite sheet, EPCs sheet and BMSCs sheet were respectively implanted into the defects of the alveolar bone in ovariectomized rats. Rats with no implantation served as control group. Repaired alveolar bone was assessed by gross examination, histological observation and micro-CT scan at 2, 4, 8 weeks after operation.
RESULTS AND CONCLUSION: BMSCs/EPCs composite sheet has greater osteogensis activity and bone repair capacity than BMSCs or EPCs sheet alone.
