1·It was found that the cytoplasm of the protoplasts were rich in very dense and fine actin microfilament cables.

研究结果发现洋葱鳞茎内部细胞的细胞质内存在极丰富而精细的肌动蛋白微丝束。

2·Objective: To investigate the effect of cytomegalovirus(CMV) infection on actin and microfilament in human embryo fibroblast cells(HF) and its relationship with CMV replication.

目的：探讨巨细胞病毒（CMV）感染对人胚成纤维细胞（HF）微丝骨架影响及与病毒复制状态的可能关系。

3·As the important part of cytoskeleton, microfilament skeleton is composed of actin and actin-binding proteins, and widely exists in eukaryotic cells.

微丝骨架是细胞骨架的重要组成部分，它由肌动蛋白和肌动蛋白结合蛋白组成，广泛存在于真核细胞中。
