Cell migration; Cell-cell and cell-substrate interaction

The morphology of cells, organs and whole organisms is determined by the generation of forces on the immediate environment, which is either extracellular matrix or adjacent cells. We are currently engaged in studies to understand the detailed molecular mechanisms involved in a variety of phenomena from cancer metastasis to brain function. Further, we are developing several new tools and protocols for measuring cell forces at the molecular level, which are revealing many new aspects of how cells can both  generate and respond to external forces.We have an effort underway to define quantitatively the steps involved in cell adhesion to and spreading on a matrix-coated surface. Using a variety of cell lines that are missing proteins in various motility pathways, we are determining the quantitative changes in the spreading process. This will enable us to generate a detailed model of the process of spreading that will be a model for further studies of how cells differentiate, regenerate tissues or metastasize.

Hailing from Columbia University, Prof Michael Sheetz has more than 40 years’ experience in the biomedical field. Introduced to Singapore by Prof Hew Choy Leong of the National University of Singapore’s Department of Biological Sciences, Prof Sheetz was sought to lead an RCE project. This resulted in a two-year effort to organise and submit a proposal on Mechanobiology where Prof Sheetz set the theme and direction of the Mechanobiology Institute (MBI). As Executive Director of the MBI, he will be spending nine months a year in Singapore to oversee the Institute’s programmes.
