Conclusion: Since the BMSCs of rabbit cultured can proliferate well and can be induced to differentiate into osteoblasts in vitro, they can be used as test cells to evaluate the cell histocompatibility of bone defect substitution materials. 结论:兔骨髓基质干细胞的体外增殖能力强,可诱导为成骨细胞,可作为骨缺损材料细胞相容性研究的受试细胞。
Using the graph modular as the basic cell of product structure modelling, we put forward a graphics substitution approach to edit the structure model, and present a set of useful methods to operate the graph modular. The maping procedure from function to structure is realized. 本文以图形单元作为产品结构建模的基本单位,提出了进行产品结构模型编辑的图形置换技术,给出了实用、方便的单元操作方法,实现了基于功能设计图形结构的过程。
