丝状伪足

扫描电镜发现Pc滋养体丝状伪足和微绒毛稀疏、变短甚至脱落，表膜出现缺损。

Under SEM , filopodia and microvilli became sparse , short and fell off , a breach appeared in the surface membrane in Pc trophozoites .

结果在三维的水平面上，vinculin与Factin的免疫反应活性在P领域和C领域的部分区域重合，在P领域伸展方向前端和丝状伪足内免疫反应活性最强。

Results In the horizontal direction , the immunoactivity of vinculin and F-actin partly overlapped in the C-domain and P-domain . The strongest immunologic reactions of them occurred in the head of P-domain stretching area and filopodia .

结果：培养24小时的生长端丝状伪足不断运动改变生长端的形态，pp60cSrc（+）的免疫反应活性分布在神经细胞的核周体、神经突起、生长端部分领域和丝状伪足；

Results : Filopodia in the growth cones , which had been cultured for 24 h , moved unceasingly , and the morphological characteristics of growth cones changed . Immunoactivity of pp 60c-src ( + ) distributed around perikaryon , nerve processes , parts of growth cones and filopodia .

迁移细胞表面有众多丝状伪足。

The surface of migration cells exhibited numerous filopodia .

细胞中多种骨架亚结构，如微绒毛，应力纤维，静纤毛，丝状伪足等，均由肌动蛋白纤维束构成。

Multiple skeletal substructure cells , such as microvilli , stress fibers , stereocilia , filopodia , etc. , are formed by F-actin bundles .

感染1天后，部分细胞丝状伪足缩短变粗，另部分则丝状伪足几乎全部消失，细胞表面略现皱褶和分布着疏散的手指样结构。

One day after infection , the filopodia became somewhat thick and short in a portion of cells , while in the others the filopodia even virtually disappeared and the surfaces seemed to be undulated with varying number of scattered " fingerlike " projections .

破骨细胞细胞核核大，4～6个，胞浆伸出丝状或片状伪足。

Osteoclasts had 4 to 6 big nuclei , and cytoplasm extended pseudopodia of filament or sheet shape .
