... the first molecular evidence whereby sensory organs direct the development of the associated non-sensory components, the semicircular canals, in vertebrate inner ears. Here, we fate map the vertical canal pouch in chicken using DiI. We identify a canal genesis region immediately adjacent to the sensory...

...Yohanns Bellaïche; Olivia Beaudoin-Massiani; Isabella Stüttem; François Schweisguth Cell fate diversity is generated in part by the unequal segregation of cell-fate determinants during asymmetric cell division. In the Drosophila bristle lineage, the sensory organ precursor (pI) cell is polarized...

... Drosophila melanogaster ( Dm ) about 200 million years ago, and examined their expression patterns. We found that an ac-sc homologue of Anopheles , Ag-ASH , is expressed on the dorsal medial notum at the sites where sensory organs emerge in several domains that are identical to those of the pnr homologue, Ag...

... as on the wing blade, but we did not attempt to correlate these with specific sensory organs ( Fig. 2 A,B). Expression is first observed in the DC stripe at, or just prior to, pupariation. It is rapidly followed by expression in the posterior domain of the prospective AC stripe, the posterior most IA and SA...

..., depending on the sensory organ type. Numb, which is asymmetrically localized in the multipotent cell that produces the glial precursor, induces glial cells at the expense of neurons. Thus, a cell- autonomous mechanism inhibits Notch signaling. * Author for correspondence (e-mail: angela@titus.u...

... Otx1 and Otx2 are normally expressed. These results suggest that both Otx genes play important and differing roles in the morphogenesis of the mouse inner ear and the development of its sensory organs. ‡ Author for correspondence (e-mail: wud@nidcd.nih.gov ) * Present address: Children’s...

...G. Venugopala Reddy; Veronica Rodrigues ABSTRACT Specification of cell fate in the adult sensory organs is known to be dependent on intrinsic and extrinsic signals. We show that the homeodomain transcription factor Prospero (Pros) acts as an intrinsic signal for the specification of cell fates...

...Shuwen Wang; Susan Younger-Shepherd; Lily Y.

The sensory organ precursor cell first divides...
