细胞标志 meaning in English
cell marker
Examples
- Effect of lead acetate on special markers of osteoblasts in rats
铅对大鼠成骨细胞标志物的影响 - The astrocyte marker gfap and oligodendrocyte marker mbp were not detected . nor the endoderm and mesoderm markers
胶质细胞标志基因gfap 、 mbp未检测到，其他胚层的标志性基因也没有表达。 - But they give expression to nestin and receptors of epidermal growth factor ( egf ) and basic fibroblast growth factor ( bfgf ) ; secondly , they possess the capacity for self - renewal ; thirdly , they possess the capacity for mul tipotential ity , namely differentiating into various cells in the central nervous system
同时表达神经干细胞标志性蛋白-神经巢蛋白( nestin ) ； ( 2 )自我更新能力； ( 3 )多潜能性，即能分化成神经系统的各种细胞。 - Thus the objective of this study is to find some ways to improve the efficiency of cell therapy , that is . to optimize the microenvironment of nscs and in turn prompt them to functinally repair abnormal cns . in the first part , optimization of x - gal staining method , which is correlated with ph , incubating time , perfusion and some other parameters , was successfully got and used in the subsequent experiment , viz , comparing the behaviours of primary nscs and immortal nsc line after transplantation
鉴于此，为寻求各种方法提高移植效率，改善外源nscs存活及分化，进而促进其实现功能性替代，为临床nscs治疗提供理论基础，本实验进行了以下三部分的研究：实验第一部分研究了以lacz作为移植细胞标志基因时x - gal染色的影响因素，并得出排除非特异背景的优化条件。 - There was no difference in other biologic characteristic of mscs between the two separation method , such as cell anchorage ratio and clone formation ratio . ( 2 ) plga film presented uniformity frame with no protuberance and fissure under scanning electron microscopy ( sem ) . big aperture with smooth wall and average 400 m i n size running - through each other was observed in porous plga substrate , around the big aperture there were many round micropores about 5 m size . all of the structure were equal and uniform , which satisfied the further research work . ( 3 ) mscs adhesion at earlier time was promoted by biotiegenrafter 3h , cell number was ( 1 . 5 0 . 18 ) 105 in the plga film coated with biotiegen group , which was significantly higher than that in plga film group ( p < 0 . 01 ) and higher than that in coverslip group ( p < 0 . 05 ) , which cell number was ( 1 . 04 0 . 21 ) 105 . after 6h and 12h biotiegen could not promote cell adhesion , and cell proliferation and alkaline phosphatase ( alp ) activity were not promoted dramatically during 9 days . ( 4 ) cell adhesion was promoted by fibronectin or collagen type i
G ） i型胶原、纤维粘连蛋白促进细胞增殖，细胞接种后3 、 6 、 gd三个检测时间点，实验组细胞均明显高于对照组。与1型胶原相比，纤维粘连蛋白刺激作用更强。 ） i型胶原、纤维粘连蛋白尚能诱导mscs细胞向成骨细胞分化，不仅表达成骨细胞标志物ocn 、 alp 、 opnmrna ，而且碱性磷酸酶活性明显增高，碱性磷酸酶及钙结节7第四军医大学博士学位论文一染色均强阳性， i型胶原组mscs细胞碱性磷酸酶活性较fn组更高，有显著性差异；同时，兔疫组化染色表明，经纤维粘连蛋白作用的mscs1型胶原表达阳性。
