Giant cell tumor of bone is a kind of common bone tumor,which has characteristics of high recurrence rate and invasion.recently,tumor vessel angiogenesis has been the warm spot of research.genesis,development and metabasis of solid tumor have close relationship with tumor vessel angiogenesis; extracellular matrix degradation is the key point for tumorous infiltration and metabasis;the significant biology characteristic of tumor cell is the disorder of tumor cell differentiation and apoptosis.the correlated research has very important significance for judging gct prognosis and guiding therapy.

骨巨细胞瘤（giant cell tumor of bone，gct）是一种常见骨肿瘤，由于其高复发率和强侵袭性，备受临床骨科工作者的关注。骨巨细胞瘤血管生成是近年来研究热点，实体瘤的发生、发展及转移与肿瘤的血管生成密切相关；细胞外基质降解在肿瘤的浸润和转移中起到关键作用；肿瘤细胞的分化凋亡障碍与无限增殖能力是肿瘤细胞的重要生物学特征。骨巨细胞瘤生物大分子研究的不断深化对判断gct的预后及指导治疗有重要意义。

Prussian blue staining showed numerous blue stained fine particles in the cytoplasm of 99% BMSCs.

普鲁士蓝染色结果显示99%以上骨髓基质细胞的胞质内出现细小的蓝色铁颗粒。

In contrast to conventional methods, a novel cell sheet-based technique has been proposed .This technique intend to achieve high cell density and function by layering confluent viable cell sheets without the use of acellular scaffolds that limit mass transport. Using thermo-sensitive cell culture surfaces, confluently cultured cells spontaneously detach as intact sheets simply by reducing the culture temperature.

与传统方法相比，有学者提出了一种新的以细胞层为基础的组织工程技术，这种技术作为一种新的选择，利用温敏性培养皿，经简单的温度变化，可以非损伤性的一起获得完整的培养细胞层及其所沉积的细胞外基质，从而避免了使用蛋白水解酶。

To solve the problem and improve the safety of gene therapy, we used microencapsule, a insulation tool of cell transplantation immunity, to encapsule human fibroblastlike bone marrow stroma cells transfected by part of CEA gene and produced microencapsulated CEA transgeneic cell vaccines; we also studied the expression of vaccine in mouse body as well as its immunologic characteristics.

为解决上述问题、提高基因治疗的安全性，本研究采用细胞移植免疫用隔离工具-微胶囊包裹转染部分CEA基因的人成纤维样骨髓基质细胞HFCL，制备出CEA微囊化转基因细胞疫苗，并进行了疫苗在小鼠体内的表达及其免疫学性质的研究，探讨该疫苗应用于CEA阳性肿瘤治疗的可能性，并为进一步的临床应用研究奠定了基础。
