Hannah publishes WIREs Developmental Biology review

Congratulations to postdoc, Frank Mason, for the recent publication of his paper, “Apical domain polarization promotes actin-myosin assembly to drive ratchet-like apical constriction” on Nature Cell Biology. In the paper, Mason et al. show that the signals that regulate contractile forces in constricting cells exhibit a spatial organization within the apical domain of the cell. Signals that activate myosin motors are polarized to the center of the apical domain. Actin polymerization in this domain suppresses junctional protein localization, restricting junctional proteins to cell-cell interfaces. Thus, a “radial” cell polarity is established, which is shown to be important for apical constriction.

Hannah received her Ph.D. from the Institut Curie in Paris, France. Her Bachelor’s degree is in Physics and she published a really cool paper on cells walking a “tightrope.” She is interested in collective cell behavior changing tissue shape.

Congratulations Soline on the publication of a book chapter Mechanical Force Sensing in Tissues!

Graduate student Clint Ko and Undergraduate Prateek Kalakuntla publish MBoC paper on how mitotic entry can repress ‘active’ contractility and result in relaxation that promotes neighboring tissue folding.

Congratulations Dr. Jackson on defending your PhD and getting a postdoc position in Germany.  Best of luck.

Congratulations to postdoc, Soline Chanet, for being awarded an EMBO Long-Term Fellowship.
