摘要:

背景:国内外许多研究者一直寻找理想的种子细胞与合适的支架材料复合,试图模拟接近正常生理功能的组织工程化尿路替代物。
目的:探讨骨髓间充质干细胞与兔膀胱脱细胞基质支架的生物相容性。
方法:采用密度梯度离心法分离培养兔骨髓间充质干细胞,将第3代兔骨髓间充质干细胞接种到兔膀胱脱细胞基质上进行复合培养,每天进行细胞计数,连续12 d,绘制细胞生长曲线,以单独培养骨髓间充质干细胞为对照组。
结果与结论:骨髓间充质干细胞成功种植到膀胱脱细胞基质上,倒置显微镜下可见骨髓间充质干细胞从膀胱脱细胞基质边缘爬出,膀胱脱细胞基质周围有大量长梭形骨髓间充质干细胞生长。接种5 d内,两组细胞均呈现出平缓生长的状态,接种6-9 d,生长曲线逐渐变得陡峭,细胞呈倍数状态进行分裂生长,速度较快,接种10-12 d,再次趋于平缓状态。两组细胞生长曲线基本重合,可推断兔骨髓间充质干细胞与膀胱脱细胞基质生物相容性良好。

Abstract:

BACKGROUND: In the repair of urinary tract defects, we have been actively trying to construct the urinary tract substitutes with normal physiological function through combining ideal seed cells and proper scaffold materials by tissue engineering method.
OBJECTIVE: To investigate the biocompatibility of bone marrow mesenchymal stem cells with rabbit bladder acellular matrix scaffold.
METHODS: Rabbit bone marrow mesenchymal stem cells were isolated and cultured using density gradient centrifugation method. Passage 3 rabbit bone marrow mesenchymal stem cells were cultured on the rabbit bladder acellular matrix. The cells were counted every day for 12 days, to drawn a cell growth curve. Bone marrow mesenchymal stem cells cultured alone were used as control group.
RESULTS AND CONCLUSION: Bone marrow mesenchymal stem cells were successfully seeded onto the bladder acellular matrix. Under the inverted microscope, the cells grew out of the bladder acellular matrix, and a great amount of long spindle-shaped cells were found around the bladder acellular matrix. With 5 days of inoculation, the cells in the two groups grew gently; at 6-9 days, the cell growth curve gradually became steeper, and the cell division and growth were increased exponentially; at 10-12 days, the cells recovered to a gentle state. Cell growth curves in the two groups were basically coincident, suggesting that rabbit bone marrow mesenchymalstem cells have good biocompatibility with the bladder matrix.
