图1:实验设计的示意图。实验研究时间表的概述。人类的组织工程骨构建(hTEBC)是由播种人类成骨细胞(滚铣刀)二次磷化钙融化electrowritten医疗级聚已酸内酯(mPCL)脚手架床单孔隙度为95%。滚铣刀形成致密细胞/细胞外基质(ECM)网络在整个脚手架建筑/ 2周前文化条件转换为11周成骨的媒体。植入前一周,星型聚乙二醇(sPEG)肝素凝胶包含滚铣刀的准备,人类间充质基质细胞(msc),和人类脐静脉内皮细胞(HUVECs)和培养形成capillary-like网络。共有n = 10小鼠被用于这项研究。在皮下植入sPEG-heparin凝胶之前在vitro-engineered一起夹在两个二次结构。c NSG的左后卫雄性老鼠收到体外工程构造播种滚铣刀和结合滚刀细胞在纤维蛋白胶(n-10老鼠),而右后卫收到不结果实的支架与cell-loaded sPEG-heparin凝胶(n = 10老鼠)。cell-laden和体外无细胞工程结构是结合重组人骨形态形成protein-7 (rhBMP-7)和纤维蛋白胶立即植入前。骨头被允许开发前8周intraprostatic注入和监控使用x射线。 d Humanization of the mouse prostate was performed via injection of PC-3-luc cells together with prostate lymphatic and blood vessel endothelial cells (BVECs) and PCa-derived fibroblasts (CAFs) performed in n = 5 mice, whereas the non-humanized group received an intraprostatic injection of PC-3-luc cells alone performed in n = 5 mice. e Growth of the primary prostate tumor and metastasis to distant organs were monitored weekly using in vivo bioluminescent imaging for 10 weeks.
