We have analyzed the distribution of intermediate filaments (IF) in the cytoplasm of mature decidual cells of mice. IF were scattered throughout the cytoplasm of these cells although there was a preferential accumulation around the nuclei. In many cells a large area of the cytoplasm was occupied by a rich network of IF that extended from the perinuclear region toward the cell surface. Thin bundles of IF crossed the cytoplasm without a preferential orientation. IF were also seen in close association with nuclear pore complexes, gap junctions, mitochondria, and lysosomes. A very developed network of IF surrounded phagosomes that contained collagen fibrils. Longitudinal and cross sections of these phagosomes showed a very close association of IF with the phagosome membrane.
我们分析了小鼠成熟蜕膜细胞胞质中中间丝（IF）的分布情况。中间丝散布于这些细胞的整个胞质中，不过在细胞核周围有优先聚集现象。在许多细胞中，胞质的大片区域被丰富的中间丝网络占据，该网络从核周区域延伸至细胞表面。细的中间丝束横穿胞质，没有优先取向。中间丝还可见与核孔复合体、间隙连接、线粒体和溶酶体紧密相连。一个非常发达的中间丝网络围绕着含有胶原纤维的吞噬体。这些吞噬体的纵切面和横切面显示中间丝与吞噬体膜紧密相连。
