在相差显微镜和电镜下,培养中的贴壁成纤维细胞呈长梭形、轴向排列、胞质中有许多单个或成束排列的微丝;而悬浮的成纤维细胞呈圆形、单个或呈簇状,胞质中微丝很少或未见。观察结果表明:微丝与成纤维细胞的贴壁生长、细胞呈长梭形、轴向排列有密切关系。 Under phase contrast microscopy and electron microscopy, adherent fibroblasts in culture are elongated spindles, axially arranged, with many single or bundled filaments in cytoplasm; while suspended fibroblasts are round, single or Clustered, little or no microfilaments in the cytoplasm. The observational results show that the microfilaments are closely related to the adherent growth of fibroblasts, long spindles and axial arrangement of cells.
