Welcome Clint Ko

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.

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

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 graduate student Claudia Vasquez on her publication “Dynamic myosin phosphorylation regulates contractile pulses and tissue integrity during epithelial morphogenesis” in The Journal of Cell Biology. Claudia’s paper was also highlighted in a video interview with the JCB news editor.

Congratulations Fernando on a productive summer and successfully presenting your poster at the end of summer program. We look forward to seeing what you do in the future!
