The Brazilian Buriti oil presents low extraction costs and relevant antioxidant properties. Thus, this work aimed to analyze Buriti oil biomaterial (BB), within its physicochemical properties, biocompatibility and cellular integration, with the purpose to the use as a growth matrix for Goat Wharton's jelly mesenchymal stem cells. Biomaterials were produced from Buriti oil polymer (), for it's characterization were performed Infrared Region Spectroscopy (FTIR) and Thermogravimetric Analysis (TG and DTG). The biointegration was analyzed by Scanning Electron Microscopy (SEM) and histological techniques. In order to investigate biocompatibility, MTT (3-(4,5-dimetil-2-tiazolil)-2,5-difenil-2H-tetrazólio) test and hemolytic activity tests were performed. The activation capacity of immune system cellswas measured by phagocytic capacity assay and nitric oxide synthesis . The BB presented an amorphous composition, with high thermal stability and high water expansion capacity, a surface with micro and macropores, and good adhesion of Wharton's jelly mesenchymal stem cells (MSCWJ). We verified the absence of cytotoxicity and hemolytic activity, in addition, BB did not stimulate the activation of macrophages. Proving to be a safe material for direct cultivation and also for manufacturing of compounds used for in vivo applications.
巴西Buriti油提取成本低且具有显著的抗氧化特性。因此,本研究旨在分析Buriti油生物材料(BB)的物理化学性质、生物相容性和细胞整合情况,以期将其用作山羊脐带华通氏胶间充质干细胞的生长基质。生物材料由Buriti油聚合物制成,通过红外光谱(FTIR)和热重分析(TG和DTG)对其进行表征。通过扫描电子显微镜(SEM)和组织学技术分析生物整合情况。为了研究生物相容性,进行了MTT(3-(4,5-二甲基-2-噻唑基)-2,5-二苯基-2H-四氮唑)试验和溶血活性试验。通过吞噬能力测定和一氧化氮合成来测量免疫系统细胞的激活能力。BB呈现无定形组成,具有高热稳定性和高水膨胀能力,表面有微孔和大孔,且脐带华通氏胶间充质干细胞(MSCWJ)的粘附性良好。我们证实了其无细胞毒性和溶血活性,此外,BB不会刺激巨噬细胞的激活。证明其是一种用于直接培养以及制造体内应用化合物的安全材料。
