Thin and thick sections of both physiologically active and physiologically passive iridophores from a range of vertebrate species have been examined by electron microscopy at 60 kV and at 1,000 kV. All iridophores studied have been found to contain 65-A filaments linking successive crystals in their parallel stacks; their orientation in the cell is shown in stereo pairs of 0.25-microm sections obtained from high voltage microscopy. In addition, several of the physiologically passive iridophores contain 100-A filaments in varying numbers. It is suggested that the thin filaments might be iridophore actin and play a role in the movement of iridophore components, and that the 100-A filaments might play a cytoskeletal role in the iridophores in which they occur.
利用电子显微镜在60千伏和1000千伏的电压下,对一系列脊椎动物物种中生理活性和生理惰性的虹彩细胞的薄切片和厚切片进行了检查。研究发现,所有被研究的虹彩细胞都含有65埃的细丝,这些细丝将其平行堆叠中的连续晶体连接起来;从高压显微镜获得的0.25微米切片的立体对中显示了它们在细胞中的取向。此外,一些生理惰性的虹彩细胞含有数量不等的100埃细丝。有人认为,这些细的细丝可能是虹彩细胞肌动蛋白,在虹彩细胞成分的移动中起作用,而100埃的细丝可能在含有它们的虹彩细胞中起细胞骨架的作用。
