Module 8: Figure Drosophila planar cell polarity



Functional assay of planar cell polarity in Drosophila.

A. In the wild-type abdomen, all the bristles are orientated in an anterior–posterior direction as illustrated by the yellow arrows. B. A small Frizzled clone reverses the polarity of cells posterior to the clone (blue arrows). C. A small clone overexpressing Fat (green cells) located in a background of cells deficient in Flamingo. The somewhat haphazard bristle orientation of the Flamingo cells near the clone is altered so that several layers have their bristles pointing towards the clone both in the anterior and posterior regions (blue arrows). Information contained in Figure 2 from Lawrence et al. (2007) was used to construct this figure.
