Abstract

The polarity of thin filaments in relation to thick filaments in developing muscle cells in vitro was investigated. The majority of thin filaments exhibited the right polarity and spatial position similar to that seen in mature myofibrils. It appears that the interaction between thick and thin filaments exists in the initial phases of myofibrillogenesis. Cortical microfilaments are found to have their polarities arranged randomly.

摘要

研究了体外培养的发育中肌细胞中细肌丝相对于粗肌丝的极性。大多数细肌丝表现出与成熟肌原纤维中所见相似的正确极性和空间位置。看来粗肌丝和细肌丝之间的相互作用存在于肌原纤维形成的初始阶段。发现皮质微丝的极性是随机排列的。
