摘要:
[摘要]目的：寻找更高效的婴幼儿血管瘤内皮细胞培养方法，为婴幼儿血管瘤的研究提供基础的科研保证。方法：选取增生
期婴幼儿血管瘤手术标本，采用组织块贴壁法与酶消化法结合进行原代培养；二代细胞进行流式分选，取CD31阳性的细胞继
续培养。分别进行细胞形态学观察、细胞表面标记物免疫荧光鉴定、细胞表面标记物流式鉴定。结果：培养48～72h清晰可
见组织块周围细胞游出，细胞核清晰，细胞呈长梭形及多边形，2周左右部分可形成“血管腔样”结构，20d可铺满平传代；
细胞流式测定CD31阳性率达98.4%，VWF与CD31双阳率90.3%，免疫荧光染色CD31、VWF均呈阳性表达。结论：组织块与消化结
合法经流式分选后可获得高纯度的内皮细胞，为下一步研究婴幼儿血管瘤增生消退机制奠定了基础。

Abstract:
Abstract: Objective To explore the endothelial cell culture method of more efficient infant hemangioma ,to provide the
basic research guarantee for the research of hemangioma of infants. Methods In order to select the surgical specimens of the
hemangioma of the hyperplasia, the primary culture was carried out by means of Tissue block adherent and enzyme digestion.
Two generations of cells were selected for flow separation, and CD31 positive cells continued to be cultured.It were respectively
carried out to observe the cell of morphology, immunofluorescence identification of cell surface marker, of fluid identification
of cell surface marker. Results The cells in the tissue block around the tissue block could be clearly visible from 48-72 hours.
The nuclei were clear, the cells were long fusiform and polygons, and the portion could form "blood vessel cavity" structure in
about 2 weeks. The positive rate of CD31 was 98.4%, the VWF and CD31 were 90.3%, and the immunofluorescence staining
CD31 and VWF were positive. Conclusion The high purity endothelial cells can be obtained after the flow separation of the
means of tissue block and digestive association, which lays the foundation for the next study on the mechanism of proliferation
and regression of hemangioma of infants.
