| 摘 要： | 为了研究体外培养仔猪胰腺细胞的适宜条件,试验选取1日龄的仔猪胰腺组织置于冰上清洗、修剪,对消化酶、离心方式、培养皿铺被方式、培养液及添加不同促生长因子等多种因素进行筛选和优化。结果表明:0.25%胰酶消化所获得的细胞强于0.1%胶原酶消化获得的细胞,细胞清亮,易于生长;采用500 r/min离心5 min、多次离心所获得的细胞较Percoll不连续密度梯度离心和5%BSA等密度梯度离心所获得的细胞贴壁率高,生长能力强,易于培养传代;采用0.1%明胶或20μg/mL的层黏连蛋白铺被培养皿均比无铺被的培养皿获得更多的贴壁细胞;以RPMI 1640、M199、F12、L-DMEM多种培养液培养仔猪胰腺细胞,表现出多种细胞形态和生长趋势;在基础培养液中添加上皮生长因子、角质化生长因子、β-巯基乙醇和白血病细胞抑制因子、转铁蛋白与亚硒酸盐混合试剂等促干细胞增殖因子可促进不同形态细胞的增殖。说明按此方式培养可获得大量、多种细胞形态的仔猪胰腺祖/干细胞。

| Abstract: | To study suitable culture-conditions for pancreatic cells in neonatal piglets in vitro.The pancreatic tissue of neonatal piglets was collected,and washed bloodiness,and took off the fat,and cut into pieces all on the ice.Multiple factors were screened and optimized which were digestive-enzymes,centrifugal-methods,coated-mediums,basic-media,and many factors.The results indicated a culture system of pancreatic cells in neonatal piglets as follow: The digested cells with 0.25% trypsin were clearer than 0.1% co... |
