Welcome Anthony McDouglal!

Mingmar joined us this summer from the University of Alabama at Birmingham as our new Technical Associate, welcome!

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.

Congratulations Natalie on publishing her work “Actomyosin-based Tissue Folding Requires a Multicellular Myosin Gradient” in Development. Natalie discovered that a tissue-wide gradient in transcription and resulting contractility is necessary to fold a tissue. We had fun collaborating with Pearson Miller and the Dunkel Lab on this project.

Congratulations Mary Ann Collins on publishing review article on plant and animal morphogenesis in Developmental Cell!

Congratulations to graduate student, Juana De La O, on passing her qualifying exam.

Graduate students Anna Yeh and Jaclyn Camuglia publish book chapter on morphogenesis titled Extracellular Tension and Tissue Morphogenesis.
