摘要:

背景:目前婴幼儿血管瘤的发病机制尚不明确,通过体外培养的血管瘤内皮细胞进行发病机制的研究为当前研究的热点。
目的:探讨血管瘤内皮细胞体外培养的方法并观察其生物学特性。
方法:采用组织块贴壁法原代培养血管瘤内皮细胞, 第Ⅷ因子相关抗原、CD31、CD34免疫组织化学SP法鉴定内皮细胞并测出内皮细胞纯度;观察血管瘤内皮细胞的生物学特性。
结果与结论:成功培养出血管瘤内皮细胞,第Ⅷ因子相关抗原、CD31、CD34均为阳性。检测纯度:CD34(+)数为(68.35±3.58)%。细胞形态为较规则的圆形、椭圆形或多角形,呈现特有“铺路石”特征,而且还具有血管瘤内皮细胞特有的“管腔形成”现象。结果表明,组织块贴壁法能成功培养较纯的婴幼儿血管瘤内皮细胞,传代后第3,4代最适于体外实验研究。

Abstract:

BACKGROUND: Currently, the pathogenesis of infantile hemangioma is not yet clear, and therefore, studies on tumor pathogenesis through in vitro culture of endothelial cells from hemangiomas have become a research focus.
OBJECTIVE: To explore an in vitro culture method for infantile hemangioma endothelial cells and to observe the biological characters of cultured cells.
METHODS: The endothelial cells of infantile hemangioma were cultured by tissue explant method. Immunohistochemical staining of anti-CD31, anti-CD34 and anti-factor VIII associated protein was performed to identify the cultured cells, respectively. Purity of endothelial cell was detected with CD34. The biological characters of the cultured cells were observed.
RESULTS AND CONCLUSION: Vascular endothelial cells were successfully cultivated and positive for CD31, CD34 and anti-factor VIII. The proportion of CD34+ cells was (68.35±3.58)%. The cells were round, oval or polygonal, and cell boundaries were clear. Endothelial cell-specific “paving stone” feature could be observed after cell fusion. These findings indicate that endothelial cells of infantile hemangioma can be isolated and cultured successfully by tissue explant method, and cells at passages 3-4 are the most suitable for in vitro experiments.
