AIM: There is an increasing need for an appropriate and readily-available material to reconstruct large bone defects, one of the most significant problems in the dental and maxillo-facial fields. The in vitro study examines the effects of OSTEOPLANT ANGIOSTAD, a product developed to increase osteoinductivity. METHODS: The product's biological properties were assessed by examining: the viability of cultured bone-marrow mesenchymal stem cells (MSC) through the methylthiazol tetrazolium assay; transforming growth factor (TGF)-b release by these cells through the enzyme-linked immunosorbent assay (ELISA) and the migration capacity of MSC and endothelial cells, by the in vitro wound closure test and transwell-migration assay, respectively. RESULTS: OSTEOPLANT ANGIOSTAD preserved MSC's viability and improved their capacity to release TGF-b1. It also increased in vitro wound healing by MSC and migration of endothelial cells. CONCLUSION: The results show that, since it increases the production by MSC of proangiogenic factors such as TGF-beta and promotes endothelial cell migration, OSTEOPLANT ANGIOSTAD may be an appropriate adjunct to accelerate the osteointegration of bone substitutes.

Abstract

AIM: There is an increasing need for an appropriate and readily-available material to reconstruct large bone defects, one of the most significant problems in the dental and maxillo-facial fields. The in vitro study examines the effects of OSTEOPLANT ANGIOSTAD, a product developed to increase osteoinductivity. METHODS: The product's biological properties were assessed by examining: the viability of cultured bone-marrow mesenchymal stem cells (MSC) through the methylthiazol tetrazolium assay; transforming growth factor (TGF)-b release by these cells through the enzyme-linked immunosorbent assay (ELISA) and the migration capacity of MSC and endothelial cells, by the in vitro wound closure test and transwell-migration assay, respectively. RESULTS: OSTEOPLANT ANGIOSTAD preserved MSC's viability and improved their capacity to release TGF-b1. It also increased in vitro wound healing by MSC and migration of endothelial cells. CONCLUSION: The results show that, since it increases the production by MSC of proangiogenic factors such as TGF-beta and promotes endothelial cell migration, OSTEOPLANT ANGIOSTAD may be an appropriate adjunct to accelerate the osteointegration of bone substitutes.
