The ability of eukaryotic cells to migrate within living organisms underlies a wide range of phenomena in health and disease.
When properly regulated, cell migration enables morphogenesis, host defense and tissue healing. When regulation fails, however, cell migration mediates devastating pathologies such as cancer, vascular disease and chronic inflammation. Our research focuses on understanding the fundamental biophysical mechanisms underlying migration both at the single cell level and at the tissue level.
Making cellular forces visible
To study cell and tissue dynamics we develop new technologies to measure physical forces at the cell-cell and cell-matrix interface. By combining these technologies with computational analysis of cell shape and velocity we obtain a full experimental characterization of epithelial dynamics during tissue growth, wound healing and cancer cell invasion.
Mechanical waves and collective cell guidance
Our new tools led to the discovery of a mechanical wave – which we called “X-wave” – that propagates through expanding cell sheets. This mechanical wave is a natural candidate to trigger mechanotransduction pathways during wound healing, morphogenesis, and collective cell invasion in cancer. We also discovered a new mechanism, plithotaxis, by which cells align their shape and migration velocity to minimize intercellular shear stresses.
Microfabrication and wound healing
Using microfabrication technologies, we designed new ways to decipher the mechanisms of wound healing. By doing so we uncovered a new understanding of how cells move and work together to close a gap in a tissue. We showed that a new mechanism applies in which cells assemble supracellular contractile arcs that compress the tissue under the wound. By combining experiments and computational modeling, we showed that contractions arising from these arcs make the wound heal in a quicker and more robust way.
Fracking epithelial layers
Epithelial sheets must be malleable enough to adopt functional shapes during morphogenesisand to quickly self-repair after damage. Yet, they must be resilient enough to ensure organ compartmentalization and to protect organisms against environmental pathogens. To study the mechanisms that regulate this fine balance between malleability and integrity we develop tools to map epithelial tension during tissue stretching. By combining these tools with computational modeling we determined the mechanisms of epithelial fracture. Intriguingly, one of such mechanisms is hydraulic fracturing or “fracking”.

When we think of wound healing, we normally think of wounds to our skin. But wounds happen inside the body in all sorts of tissues and organs, and can have implications in many chronic diseases such as diabetes and asthma. Wounds also favour cancer progression by providing a physical and chemical environment that promotes the invasion of malignant cells. Now, a group at the Institute for Bioengineering of Catalonia (IBEC) has found a new way to decipher the mechanisms of wound healing, and by doing so has uncovered a new understanding of how cells move and work together to close a gap in a tissue.

A new discovery about how cells move inside the body may provide scientists with crucial information about disease mechanisms such as the spread of cancer or the constriction of airways caused by asthma. Researchers at IBEC and Harvard School of Public Health have found that epithelial cells—the type that form a barrier between the inside and the outside of the body, such as skin cells—move in a group, propelled by forces both from within and from nearby cells to fill any spaces they encounter.
Monday’s news about the Nature Cell Biology paper ‘Chase-and-run between adjacent cell populations promotes directional collective migration’ was covered in several science and general news sites and magazines, including La Razón.

First measurements of forces driving collective cell migration unveil new principle in biology
People can be brittle, transparent, shattered, or have a heart of glass. Now these attributes seem all the more appropriate following a discovery by researchers that migrating cells in our bodies behave in a remarkably similar way to glass when it is heated and cooled.
An article by Dr. Xavier Trepat, senior researcher of IBEC´s Cellular and respiratory biomechanics group and the Department of Physiology Sciences of the University of Barcelona, contributes for the first time an experimental answer to the question of how cells move during biological processes as diverse as the development, metastasis, or regeneration of tissues.
