发布时间:2018-10-14 14:02
【摘要】:目的探讨根尖乳头干细胞(stem cells from the apical papilla,SCAP)在无支架三维培养条件下的生物学行为。方法用显微镜和HR染色观察SCAP球的大体形态,组织学结构;用免疫组化法检测SCAP球中骨涎蛋白(bone sialoprotein,BSP)和血管性血友病因子(von Willebrand factor,vWF)的表达。结果细胞球的大小对球体内部细胞的生长有影响,SCAP球具有向成骨和向内皮分化的潜能。结论无支架三维培养是一种可行的SCAP培养方法。
[Abstract]:Objective to investigate the biological behavior of apical papilla stem cells (stem cells from the apical papilla,SCAP) in three-dimensional culture without scaffold. Methods the gross morphology and histological structure of SCAP balls were observed by microscope and HR staining, and the expression of bone sialoprotein,BSP and (von Willebrand factor,vWF in SCAP spheres were detected by immunohistochemistry. Results the size of the spheres had an effect on the growth of the cells inside the spheres, and the SCAP spheres had the potential of osteogenesis and endothelial differentiation. Conclusion three-dimensional culture without scaffold is a feasible method for SCAP culture.
