摘要:

背景:鸡骨髓间充质干细胞是胚胎发育学、免疫学和肿瘤学研究重要的细胞模型,但如何大规模扩增并使其保持良好的未分化潜能是鸡骨髓间充质干细胞应用中亟待解决的难题。

 

目的:建立扩增鸡骨髓间充质干细胞的层粘连蛋白培养体系。

 

方法:将体外分离得到的鸡骨髓间充质干细胞分别接种在包被层粘连蛋白培养皿和传统二维培养皿上。经过体外扩增,比较两种培养体系下,鸡骨髓间充质干细胞的形态特征、表面标志物、扩增性能和成脂分化潜能。

 

结果与结论:层粘连蛋白培养体系和常规培养体系中骨髓间充质干细胞的形态学特征和表面标志物表达没有显著差异,但层粘连蛋白培养体系获得的骨髓间充质干细胞增殖能力和分化潜能都明显优于传统培养体系。可见层粘连蛋白培养体系能快速地扩增出大量增殖能力强和未分化性能良好的鸡骨髓间充质干细胞,为鸡骨髓间充质干细胞的进一步深入研究和应用提供生物学基础。

Abstract:

BACKGROUND: Bone marrow mesenchymal stem cells from chickens are important cell models for embryonic developmental biology, immunology and oncology research. However, it is difficult to keep bone marrow mesenchymal stem cells with good undifferentiated potential in a large-scale expansion system.

OBJECTIVE: To establish a culture system in vitro with laminin coating to expand bone marrow mesenchymal stem cells from chickens.
METHODS: Isolated bone marrow mesenchymal stem cells from chickens were seeded in laminin-coated plates and traditional two-dimensional plates, respectively. After expansion in vitro, the morphological characteristics, expression of surface markers, expansion characteristics and adipogenic differentiation of bone marrow mesenchymal stem cells in both conditions were analyzed and compared.
RESULTS AND CONCLUSION: There were no statistical differences in the morphological characteristics and expression of surface markers of bone marrow mesenchymal stem cells expanded by laminin-coated plates and traditional two-dimensional plates. But, the expansion characteristics and adipogenic differentiation of bone marrow mesenchymal stem cells cultured in laminin-coated plates were better than those in traditional two-dimensional plates. Laminin culture system could quickly amplify out of a large number of chicken bone marrow mesenchymal stem cells with better proliferation ability and undifferentiated performance. All above results indicated that a more efficient expansion system with laminin coating is established.
