Stages of cell hair construction inDrosophila

摘要

AbstractThe construction of cell hairs (trichomes) on the wings ofDrosophilaoccurs in synchrony on 30,000 cells over a period of about 20 hr. Changes in both morphology and patterns of protein synthesis occur rapidly during this time period. In this report we describe the use of stressinduced (heat shock) abnormalities in morphogenesis to provide further details on the stepwise processes of differentiation within single wing cells. A cartoon summary of the overall process and a discussion of some possible mechanisms is included.
