推测鱼类表皮中的感觉细胞
作者：
M. Whitear
皮下注射亚甲基蓝，可以染色各种硬骨鱼表皮中纺锤形或瓶形的细长细胞。Whitear1在鲦鱼（Phoxinus laevis）中发现了这种细胞，后来在其他几种淡水和海洋物种中也发现了这种细胞；应该参考那篇论文，以参考关于这个问题的为数不多的早期文献。有人认为，这些细胞是普通化学感觉的受体，但似乎更可取的是用一个术语来描述它们，而不是指示假设的功能，它们将被称为“纺锤体细胞”。由于技术原因，梭形细胞与皮肤表面和神经纤维的确切关系无法通过光学显微镜确定。
METHYLENE blue, injected subcutaneously, will stain particular elongated cells, spindle-shaped or flask-shaped, in the epidermis of various teleost fish. Such cells were found by Whitear1 in the minnow (Phoxinus laevis), and afterwards in several other species, both freshwater and marine; that paper should be consulted for references to the scanty earlier literature on the subject. It was suggested that these cells are receptors for the common chemical sense, but as it seems preferable to describe them by a term not indicative of a supposed function, they will be called ‘spindle cells’ here. For technical reasons, the exact relationship of the spindle cells to the surface of the skin, and to nerve fibres, could not be ascertained by means of the light microscope.
