Publisher Summary This chapter discusses the immunocytochemical procedures used to
observe specific tissues and cells within whole-mount preparations of Drosophila embryos …

The genes of the achaete-scute complex (AS-C) confer on cells the ability to become neural
precursors. Their expression is restricted to groups of cells, the proneural clusters, which …

Invertebrate model systems are powerful tools for studying human disease owing to their
genetic tractability and ease of screening. We conducted a mosaic genetic screen of lethal …

Insect dendritic arborization (da) neurons provide an opportunity to examine how diverse
dendrite morphologies and dendritic territories are established during development. We …

The four cells of an external sense organ in the Drosophila peripheral nervous system, the
neuron, its sheath cell, and two'outer support cells” that form the hair and socket, are derived …

During development of the Drosophila peripheral nervous system, a sensory organ
precursor (SOP) cell undergoes rounds of asymmetric divisions to generate four distinct cells …

Publisher Summary Chordotonal organs are generally found in Insecta and Crustacea. In
insects, chordotonal organs occur in great morphological diversity, and are found at nearly …

In the Drosophila peripheral nervous system, proneural genes of the achaete-scute complex
(AX) are required for formation of the precursors of external sense organs but not of …

We have investigated the role of the Notch and Wingless signaling pathways in the
maintenance of wing margin identity through the study of cut, a homeobox-containing …

Notch function is required at the dorsoventral boundary of the developing Drosophila wing
for its normal growth and patterning. We find that clones of cells expressing either Notch or …
