An early Christmas dinner to celebrate Chan Lab’s accomplishments in 2023!
As the year draws to a close, the Chan Lab celebrated the achievements and contributions by everyone (including many new faces!) in 2023 with an early Christmas dinner, and to thank them for their hard work this busy year. The Lab looks forward to more wonderful things to come in 2024!
Is Mechanosensing an Active Process?
Is Mechanosensing an Active Process?Types of MechanosensingWhen a cell periodically tests its external environment, a mechanical signal is converted to a chemical signal across the cell membrane. Adhesion receptors located on the external cell membrane [...]

Research Areas
Epithelial cell migration; microfabrication for cell mechanics; influence of the mechanical environments on cell functions; mechanotransduction
Research Interests
Our research aims at understanding how living organisms interact with their environment. In particular, we are studying the cooperation between adhesion, biomechanical and biochemical signaling for the adaptation of living organisms to changes in their environment. To probe these questions, our laboratory has developed a repertoire of micro- and nano-fabrication tools to control and measure the chemical and mechanical environment of cells. Our research programme thus focuses on the integration of novel microfabricated devices for the quantitative imaging of living organisms.
Biography
With a background in Physics, Prof Ladoux started his career at Curie Institute working on single molecule biophysics. He worked on two main problems combining statistical physics, microfabrication and molecular biology: 1) chromatin condensation in real time; 2) fluctuations of a single polymer under shear flows. After a post-doc on cell mechanics, he used his knowledge in biophysics and microfabrication to start a new subject on mechanical studies of cell migration and adhesion at the University Paris Diderot. He developed microsystems to characterise the mechanical interactions of cells with their migration support. He is currently working on rigidity sensing, collective cell migration and tissue homeostasis.

How do focal adhesions disassemble?
How do focal adhesions disassemble? Disassembly is critical during cell spreading and forward movement to allow FAs to extend outwards towards the cell periphery [1]. Disassembly of adhesions can take place as a result [...]
How do focal adhesions mature?
How do focal adhesions mature? Adhesions that manage to grow beyond the transient phase further undergo qualitative changes in a phase described as maturation. This transformation of adhesion sites into stress-fiber bound focal adhesions [...]
What are mature focal adhesions composed of?
What are mature focal adhesions composed of? Mature FAs vary in size between 1 to 5 µm and to date, more than 80 types of proteins (~150 proteins) have been located in the FA [...]
