Abstract

The shape of smooth muscle cells (SMC) was analysed using the phase contrast microscopy of cell suspensions obtained by alcohol-alkali dissociation, as well as the semithin sections prepared in perpendicular planes. The phenotype of SMC was analysed using transmission electron microscopy. The shape of SMC changes from preferentially round to preferentially spindle-like and stellate one during development. The differentiation of SMC is accompanied with the increase in the contractile apparatus content and in the decrease in the content of synthetic organelles.

摘要

利用酒精-碱解离获得的细胞悬液的相差显微镜以及在垂直平面制备的半薄切片,分析平滑肌细胞(SMC)的形态。使用透射电子显微镜分析SMC的表型。在发育过程中,SMC的形态从优先呈圆形变为优先呈纺锤状和星状。SMC的分化伴随着收缩装置含量的增加和合成细胞器含量的减少。
