In melanophores of Fundulus heteroclitus, hormone-stimulated melanosome aggregation is accompanied by cytoplasmic flow from the cellular processes to the perikaryon, and reversal of these events takes place upon hormone-induced melanosome dispersion. These cells contain parallel arrays of microtubules, the majority of which are located in the perikaryon and in cortical regions of the processes. Studies with heavy meromyosin binding demonstrated two types of actin filaments: 11 a decorated meshwork of filaments similar to those usually found in close association with plasma membranes, and 2) filaments decorated in a manner similar to that of stress fibers. There is an apparent increase in the amount of filaments during melanosome aggregation. These results are discussed in relation to intracellular movement.
在底鳉的黑素细胞中，激素刺激的黑素体聚集伴随着细胞质从细胞突起流向核周体，而当激素诱导黑素体分散时，这些过程会发生逆转。这些细胞含有平行排列的微管，其中大部分位于核周体和突起的皮质区域。用重酶解肌球蛋白结合进行的研究表明存在两种肌动蛋白丝：1）一种细丝装饰网络，类似于通常与质膜紧密相关的细丝；2）以类似于应力纤维的方式装饰的细丝。在黑素体聚集过程中，细丝的数量明显增加。结合细胞内运动对这些结果进行了讨论。
