描述了黑腹果蝇蛹翅毛形态发生的细节。最终目标是将毛发构建中使用的特定蛋白质成分与快速变化的基因表达模式中产生的特定成分联系起来，这些基因表达模式是翼细胞毛发分化时期的特征 Mitchell 和 Petersen，1981。毛发在大约 34 小时（化蛹后）突然挤出到基本完整的尺寸，随后在接下来的 4-5 小时内沉积双层角质素。接下来的 5-6 小时内，细胞和毛发形状会发生极端变化，可能与肌动蛋白合成有关。随后纤维沉积在毛发内和毛发基座上。细胞表面开始形成角质层，并持续到 60 小时范围内的某个时间。角质层似乎仅在细胞表面形成，而不是在头发或发座顶部形成。描述了与这些事件相关的蛋白质合成模式。
Details of morphogenesis of wing hairs in D. melanogaster pupae are described. The ultimate objective is to relate specific protein components used in hair construction to specific components produced in the rapidly changing patterns of gene expression that are characteristic for the period of hair differentiation in wing cells Mitchell and Petersen, 1981. Hair extrusion to essentially full size occurs quite suddenly at about 34 h (postpupariation) and this is followed by deposition of a double-layer of cuticulin during the next 4-5 h. Extreme changes in shape of cells and hairs, probably related to actin synthesis, then occur for the next 5-6 h. Deposition of fibers within the hairs and on hair pedestals follow. Formation of cuticle on the cell surface begins and continues until some time in the 60 h range. It appears that cuticle is formed only on the cell surface and not in hairs or on the top of hair pedestals. The protein synthesis patterns associated with these events are described.
