It was found that, after two days of cultivation, there were a lot of cancer ceils which adhered on to the surface of organ fragments. The cancer cells migrated on the surface of the organ and at the same time penetrated into the organ by stretching out their pseudopodia. After 3 days of cultivation, some cancer cells ...             本实验利用冷冻断裂技术和扫描电镜观察了瘤细胞侵入器官后的微细结构的变化。实验结果发现培养1至2天后很多瘤细胞附在器官表面,瘤细胞沿器官表面爬行,同时伸出丝状伪足向器官内侵入。培养3天后有些瘤细胞已侵入器官内,当瘤细胞侵入器官后以各种方式与靶细胞相接触,但仍以丝状伪足作为联络的主要微器官,它利用分支的末端变粗部分抓住靶细胞表面,呈镶嵌状态或者与对方细胞沟通融合,象直接插入似的。有些丝状伪足比在器官外时短而粗,可能因细胞之间接触的距离变短之故。一旦瘤细胞在器官内积聚成团,便形成巢状结构,它们之间多从细胞两极伸出丝状伪足相互连接,而在细胞边侧之间多数留有一定的空隙,这种空隙是否由于瘤细胞带过多的电荷相互排斥的结果,尚没有足够证据肯定或否定这个问题。本实验完成了在光学显微镜下瘤细胞浸润过程中第4、5阶段的扫描电镜观察。 文摘来源          For the first time, using SEM with cryofracture technique, the development of GC in human cerebellar hemisphere cortex was shown and discussed in this paper. In fetus arouud the 20th wk, in the deep external granular layer (EGL), it was found that some cells emitted the "Y-shape" thin projections and thick ones like short stick. These cells were supposedto be baby GC. The gathering of them in the layer means that the GC migrating process has begun. By the 32nd wk, the fracture surfaces of the cerebel lar co...             本文用扫描电镜结合冷冻断裂技术探讨了人小脑半球皮质颗粒细胞的发育。胎龄20周时,在小脑皮质外颗粒层深部的一些细胞上可发现呈“Y”形分枝的细小突起和较粗大的短柱状突起。推测这些细胞是幼稚的颗粒细胞,它们在该层的集结标志着颗粒细胞迁移过程开始。至胎龄32周左右,小脑皮质断面在扫描电镜下呈分层结构,与此同时,发现某些断面上外颗粒层趋近消失。据此推测,此时颗粒细胞的迁移过程接近终止。颗粒细胞沿Bergmann纤维构成的隧道迁移,其形态主要受隧道制约。从胎龄20周至出生时,颗粒细胞大小改变不明显。20周时,颗粒细胞表面呈脑回样结构,而到27周其面较光滑,但形成由堤状隆起构成的多边形图案。颗粒细胞在外颗粒层时产生轴突,当它们迁移至颗粒层后,其轴突向分子层生长。颗粒细胞“T”形轴突部在紧邻其胞体时,二分枝上即已分布着许多小棘。颗粒细胞原始树突形态多样,有纤毛样、覃状、分枝状等,它们或游离或与苔藓纤维末梢膨体形成突触连接。本文并对颗粒细胞体、突起及其突触连接的某些发育机制进行了初步探讨。 文摘来源          Myocardial tissues obtained from human fetuses aged from 20 to 39 weeks were studied with scanning electron microscopy (SEM), through cryofracture and standard SEM Preparations. The 3-dimensional view of the myocardial ultrastructure shows that the myocardial cells of fetus are smaller than those of the adult. Myofilaments gradually increase. Most of mitochondria are round, oval and contain well-developed cristae. At 32～39 weeks, it is obvious that many mitochondria cluster near the pole of the nucleus. Occ...             应用冷冻断裂技术结合扫描电镜的方法来观察5～10个月人胎心肌细胞的三维立体构象表明:胎儿心肌细胞较成人小。肌丝随月份逐渐增多。线粒体多为圆形、卵圆形,嵴发育好;后继月份有核周区聚集现象;偶见巨大线粒体。横管于6个月后遍及肌丝区,见有核膜攀附现象。肌质网发达,与线粒休、核膜广泛联系。根据以上结果对人胎心肌的发育进行了讨论。 文摘来源   << 更多相关文摘         相关查询: 技术》 技术 冷冻断裂 技术( 技术图书 技术物理 技术为本 技术确认 技术任务 生物测试技术 技术体现 技术生长点  对查询结果不满意
