Coordination of Cell Proliferation and Cell Fate

escargot, and snail are expressed in neuroectoderm during embryogenesis to trigger EMT in neuroepithelial cells and trans-form them into newly-delaminated neuroblasts (Ashraf et al , 1999) Wor, Escargot, and Snail also act redundantly to promote expression of the apical polarity gene inscuteable (insc) and the

Proximal to distal cell communication in the Drosophilaleg

polarity of those cells Escargot and homothorax-expressing cells also sort out from other cells in the distal domain We suggest that inductive cell communication between the proximodistal domains, which is maintained in part by a cell-sorting mechanism, is the cellular basis for an intercalary mechanism of the proximodistal axis patterning of

and Escargot are important for both the cell polarity of neuroblasts and the ability of these cells to divide [9,10] Snail, Worniu and Escargot are required for the polarity of embryonic neuroblasts

Epithelial tube fusion as a mechanism for the development of

cells contact each other and form an E-cadherin-stabilized connection regulated by Dysfusion (Dys) and Escargot (Esg) (E) Par3, aPKC, and Crumbs form an apical polarity complex at the site of fusion (F) Lumen formation begins via Rab proteins that target Par3 to the apical surface and regulate Cdc42 activation (G) The newly formed

Determination of wing cell fate by the escargotand snail

transcription factors, Escargot and Snail that are expressed in the embryonic wing disc, function as intrinsic determi-nants of the wing cell fate In escargotor snailmutant embryos, wing-speciﬁc expression of Snail, Vestigial and β-galactosidase regulated by escargot enhancer were found as well as in wild-type embryos However, in escargot

vestigial, distal less, Escargot (Esg) and snail gene products appear in specific order to establish an internal specifica-tion in the wing disc Once established, multiple genes are expressed in a precise spatiotemporal order to determine the dorsal-ventral, proximal-distal and anterior-posterior axes of the wing imaginal disc Developmental
