As the result of differential expression of embryogenesis - rela ted genes , the essence of this process has been one of remarkable issues in the plant developmental biology 植物体细胞在一定条件下可分化为胚性细胞，并通过体细胞胚的发育形成一个完整的植株，这一过程是基因差别表达的结果。
The changes of the expression of gfp in biu - 87 cell that induced by the aconitine and hab toxins , gtx were detected with fluorescence microscope , and quantitatively measured with image - pro plus software 经诱导，抗性细胞发出较强的绿色荧光，表明重组质粒pegfp - c - fos在biu - 87细胞中成功表达。
Microscopically , the valve in infective endocarditis demonstrates friable vegetations of fibrin and platelets ( pink ) mixed with inflammatory cells and bacterial colonies ( blue ) 显微镜下可见感染性心内膜炎瓣膜覆盖松脆的赘生物，其中有纤维蛋白和血小板（淡红色） ，并夹杂着炎性细胞和菌落（蓝色） 。
Experts know that cancers spread in two separate ways ? by the uncontrolled proliferation of cells , and by their refusal to undergo normal , healthy , programmed cell death , or " apoptosis . 专家们知道肿瘤发展有两种方式，通过不可控制的细胞增殖；通过它们拒绝进入正常的健康的程序性细胞死亡即凋亡。
Each time the tests were administered , blood samples were collected to assess natural killer cell activity and number of circulating lymphocyte subsets , indicators of immune system function 每次的测试都要采取受试者血样，用于评价天然杀伤性细胞的活性和循环性淋巴细胞各亚型细胞的数量，以此反映免疫系统的功能。
Thus , studies on change of inflammatory cytokines receptors expressions in the brains of immune model animals have important significance for revealing the nuclei and cells participating neuroimmunomodulation 因而，观察免疫模型动物脑内炎性细胞因子受体表达的变化对揭示脑内参与免疫调控的核团和细胞具有重要的意义。
Hypoxic preconditioning ( hpc ) , a strategy of intrinsic cytoprotection developed in biological evolution , is designed to be motivated by repetitive exposure of organism , organ , tissue and cell to condition of hypoxia 摘要缺氧预适应这一生物进化上的内源性细胞保护机制，可被机体、器官、组织和细胞的重复缺氧暴露所激发。
This is chronic osteomyelitis . note the fibrosis of the marrow space accompanied by chronic inflammatory cells . there can be bone destruction with remodelling . osteomyelitis is very difficult to treat 这是一张慢性骨髓炎的切片，髓腔内有显著纤维化伴慢性炎性细胞浸润，还可见伴有骨重建的骨破损。骨髓炎是一种难治性疾病。
Sustentacular cell was at the exterior margin of spermatogenous . in v testis , seminiferous epithelium had spermatozoon , spermatid and sustentacular cell . the sustentacular cell was fat and full of particle 支持细胞位于性细胞团的外缘，对生精细胞起支持和营养作用;在v期精巢内，精细管由大量的精子、少量的精子细胞和支持细胞构成。
