摘要: Objectives: The aim of this study was to test the applicability multipotent maxillary cells (MMC) for cell therapy concepts and evaluate their in vitro behaviour on two different bone substitutes. Material methods: Cells isolated from 10 donors were expanded using media containing human platelet lysate (HPL) replacing foetal bovine serum differentiated towards both osteogenic adipogenic lineage. Surface markers determined by fluorescence-activated sorting analysis. Calcium deposits, alkaline phosphatase (ALP) osteocalcin (OC) used as biomarkers differentiation. Oil Red O verify differentiation. The lineage undifferentiated controls further cultured natural mineral origin (BioOss®) β-tricalcium phosphate (Vitoss®) scaffolds. Scaffold efficacy migration evaluated with live imaging. Results: Isolated presented characteristics marrow (BM)-stromal could easily be clinical scales. expressed when inductive media. There no obvious differences growth between substitutes, but significantly higher OC expression observed BioOss® Both osteogenically lines ALP activity scaffolds. Conclusion: demonstrate comparable those BM-stromal cells. HPL can predictably clinical-scale expansion MMCs. grafting materials provide potential carrier loaded MMCs.
