This study examined the spatial distributions of different fiber types in the soleus muscle of control rats and in rats subjected to hindlimb unloading for 28 days. The frequencies with which muscle fibers of one type were adjacent to each other and to fibers of other types were tabulated and compared to expectations generated from Monte Carlo simulations. In the normal rat, there is a tendency for Type I fibers to avoid adjacency with each other, a tendency that persisted in the hindlimb-suspended group, despite the substantial shrinkage in size of Type I fibers. We conclude that this treatment, unlike neurogenic pathologies, does not cause any remodeling of the adjacency relations of fibers.
本研究检测了对照大鼠和后肢卸载28天的大鼠比目鱼肌中不同纤维类型的空间分布。将一种类型的肌纤维彼此相邻以及与其他类型纤维相邻的频率制成表格,并与蒙特卡洛模拟产生的预期值进行比较。在正常大鼠中,I型纤维有彼此避免相邻的倾向,后肢悬吊组中这种倾向依然存在,尽管I型纤维的尺寸大幅缩小。我们得出结论,与神经源性病变不同,这种处理不会导致纤维相邻关系的任何重塑。
