Anna Yeh and Jaclyn Camuglia publish book chapter

Congratulations to postdoc, Hannah Yevick, for publishing her review article “Quantitative Analysis of Cell Shape and the Cytoskeleton in Developmental Biology” in WIREs Developmental Biology.

Postdoctoral fellow, Hannah Yevick, published her research titled Structural redundancy in supracellular actomyosin networks enables robust tissue folding in Developmental Cell. You can hear her talk about what she discovered in the video produced by Raleigh McElvery of the MIT Biology department. Read an MIT News article on the research.

Juana De La O comes to us from the University of Chicago and the MIT Biology PhD program.

Congratulations Dr. Yeh on defending your PhD and getting a job in industry! We wish her the best of luck.

Graduate student, Jaclyn Camuglia, submitted her research “Morphogenetic forces planar polarize LGN/Pins in the embryonic head during Drosophila gastrulation” and posted a preprint. We found that morphogenetic forces are required to orient cell divisions in the Drosophila embryo through a mechanism that establishes polarity of the Pins protein.

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.
