MIT Biology graduate student, Clint Ko, is joining our labWelcome Clint Ko | June 2015

Biology graduate student, Clint Ko, is joining our lab. Clint was an undergrad at Cornell University where he worked on plant development. We are happy he has turned to the fruit fly for his next system.


Shicong 'Mimi' Xie's publication in Nature CommunicationsMimi Xie’s paper in Nature Communications | May, 2015

Congratulations to graduate student, Mimi Xie, for her publication "Intracellular signalling and intercellular coupling coordinate heterogeneous contractile events to facilitate tissue folding” in Nature Communications. In the paper, Mimi showed that cells exhibit three classes of contractile events, unconstricting, unratcheted, and ratcheted. Mimi demonstrated that cells undergo transitions between different classes of contractions, going from unconstricting or unratcheted contractions to ratcheted contractions. A transcription factor that regulates this developmental stage is important for the proper order of contractile events. It is important for cells to generate ratcheted contractions because this promotes cooperation between cells.

Frank Mason's publication in Nature Cell BiologyNature Cell Biology Paper | July, 2013

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.
