CONCLUSION: The compound composed of calcium alginate, BMSCs and growth factor might form bone and cartilaginous tissue.
结论：骨髓基质细胞-藻酸钙-生长因子复合材料能形成软骨及骨组织。
Non cartilaginous tissue and material could only prevent formation of bony bridge in small defect of growth plate and lacked ability of regenerative repair.
非软骨类组织和材料只能阻止小面积生长板缺损内骨桥形成，无再生修复能力。
Results: There was fibrous tissue in the defect of lamina after laminectomy. First formed cartilaginous tissue in fibrous, and then evolved into osseous tissues, and finally into.
结果：全椎板切除后在椎板缺损部位纤维化，首先是在骨组织缺损的边缘软骨组织形成，然后再演变为骨组织，最后形成再生椎板。
