The construction of cell hairs on the wings in developing pupae of Drosophila provides a unique system for studies of the regulation of differentiation in the absence of cell division. Early steps in hair construction are the extrusion of cell hairs and the deposition of the external impervious layer called "cuticulin." Some properties of six of the most abundant proteins that are present during the early stages of hair construction are described. These proteins make up about 40% of the total protein of the preparation.
在果蝇发育中的蛹期，翅膀上细胞毛发的构建为研究无细胞分裂情况下的分化调控提供了一个独特的系统。毛发构建的早期步骤是细胞毛发的挤出以及名为“表皮素”的外部不透水层的沉积。本文描述了毛发构建早期阶段存在的六种最丰富蛋白质的一些特性。这些蛋白质约占制剂总蛋白的40%。
