The effects of Sema3A overexpression on the proliferation and differentiation of rat gingival mesenchymal stem cells in the LPS-induced inflammatory environment.

ABSTRACT: Semaphorin3A has been identified as a potent osteoprotective factor that simultaneously inhibits bone resorption and promotes bone formation. The present study demonstrates the effect of the overexpression of Sema3A on the proliferation and differentiation of rat gingival mesenchymal stem cells (GMSCs) in the lipopolysaccharide (LPS)-induced inflammatory environment. rGMSCs were transfected with viral stocks of pLenO-GTP-Sema3A (Lv-Sema3A group) or pLenO-GTP (Lv-NC group), with rGMSCs as a control. The transfection efficiency was determined by flow cytometry. Cell proliferation was assessed using a Cell Counting Kit-8 assay. The expressions of alkaline phosphatase (ALP), osteocalcin (OCN), and runt-related transcription factor 2 (Runx2) were determined at 3, 7 and 14 days after the osteoge
