Research at the MBI

At the Mechanobiology Institute we are exploring the effects of structural micro-environments and force-induced deformations on molecules, cells and tissues in several different contexts, including the differentiation of stem cells and cancer cell pathology. The field of mechanobiology arose from the cross-roads of multiple disciplines including; cell and molecular biology, engineering, physics and computer science. New technologies such as high resolution time-lapse microscopy and micro-scale devices have vastly enhanced the study of mechanobiology, by enabling the description of complex functions at the sub-micrometer level.

By Bibhu Ranjan Sarangi, Mukund Gupta, Bryant L Doss, Nicolas Tissot, France Lam, René Marc Mege, Nicolas Borghi, and Benoit Ladoux Nano Letters. December 2016. Epub ahead of print. doi: 10.1021/acs.nanolett.6b04364 Abstract Focal adhesions (FAs) are important mediators of cell-substrate interactions. One of their key functions is the transmission of forces between the intracellular acto-myosin network and…

Non-junctional E-Cadherin Clusters Regulate the Actomyosin Cortex in the C. elegans Zygote. Current Biology, December 2016.

By Sruthi Jagannathan | Published December 15th, 2016

By Anup Padmanabhan1, Hui Ting Ong1, Ronen Zaidel-Bar2 Current Biology. December 2016. Epub ahead of print. doi: 10.1016/j.cub.2016.10.032. Abstract Classical cadherins are well known for their essential function in mediating cell-cell adhesion via their extra-cellular cadherin domains and intra-cellular connections to the actin cytoskeleton [1-3]. There is evidence, however, of adhesion-independent cadherin clusters existing outside of cell-cell…
