目前用于修复颅颌面(CMF)骨和牙齿缺损的方法需要分多个阶段进行手术,先进行骨修复,然后再植入牙种植体。我们之前发表的研究结果表明,使用接种人牙髓干细胞(hDPSC)的酪氨酸衍生聚碳酸酯支架(E1001(1K)-β-磷酸三钙)可显著形成生物工程骨。在此,我们对这一方法进行了改进,采用一种改良的TyroFill(E1001(1K)/二水磷酸氢钙(DCPD))支架支撑的钛牙种植体模型,用于同时进行骨 - 牙种植体修复。含有嵌入式钛种植体的TyroFill支架,在有(每个时间点n = 3)或无(每个时间点n = 2)接种hDPCs和人脐静脉内皮细胞(HUVECs)的情况下,在体外进行培养。然后将每个种植体植入在兔下颌骨上制备的10毫米全层临界尺寸缺损处。1个月和3个月后,获取重复构建体,并使用微计算机断层扫描(Micro - CT)、组织学和免疫组化(IHC)分析进行检测。我们的研究结果显示,在接种细胞的TyroFill构建体中,钛种植体周围有显著的新骨形成。这项研究表明,接种hDPSC/HUVEC的TyroFill支架在协同进行CMF骨 - 牙种植体修复方面具有潜在的应用价值。
Currently used methods to repair craniomaxillofacial (CMF) bone and tooth defects require a multi-staged surgical approach for bone repair followed by dental implant placement. Our previously published results demonstrated significant bioengineered bone formation using human dental pulp stem cell (hDPSC)-seeded tyrosine-derived polycarbonate scaffolds (E1001(1K)-bTCP). Here, we improved upon this approach using a modified TyroFill (E1001(1K)/dicalcium phosphate dihydrate (DCPD)) scaffold-supported titanium dental implant model for simultaneous bone–dental implant repair. TyroFill scaffolds containing an embedded titanium implant, with (n = 3 each time point) or without (n = 2 each time point) seeded hDPCs and Human Umbilical Vein Endothelial Cells (HUVECs), were cultured in vitro. Each implant was then implanted into a 10 mm full-thickness critical-sized defect prepared on a rabbit mandibulee. After 1 and 3 months, replicate constructs were harvested and analyzed using Micro-CT histological and IHC analyses. Our results showed significant new bone formation surrounding the titanium implants in cell-seeded TyroFill constructs. This study indicates the potential utility of hDPSC/HUVEC-seeded TyroFill scaffolds for coordinated CMF bone–dental implant repair.
