We aim at understanding how physical forces and molecular control modules cooperate to drive biological function.
We develop new technologies to map and perturb the main physical properties that determine how cells and tissues grow, move, invade and remodel. By combining this physical information with systematic molecular perturbations and computational models we explore the principles that govern the interplay between chemical and physical cues in living tissues. We study how these principles are regulated in physiology and development, and how they are derailed in cancer and aging.
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.
Tumour invasion by stromal forces
Cancer cell invasion and metastasis remain the leading cause of death in patients with cancer. Both processes are the result of a complex interaction between tumor cells and their microenvironment. One of our main lines of research is to study how tumours exploit the functions non-cancer cells in their microenvironment to invade and metasize. We focus on the interaction between epithelial cancer cells and Cancer Associated Fibroblasts (CAFs), the most abundant cell type in the tumour stroma. In a recent study we were able to demonstrate that CAFs guide the collective invasion of cancer cells through a physical force. This force enables CAFs to physically drag cancer cells into the surrounding tissue. Force transmission is mediated by a heterotypic interaction between two different proteins, one located on the surface of cancer cells called E-cadherin, and another expressed on the surface of fibroblasts, called N-cadherin.
Optogenetics to control cell mechanics
The recent development of optogenetic technologies offers promising possibilities to control signalling pathways with high spatiotemporal resolution. By expressing genetically encoded light-sensitive proteins, optogenetic technology enables the reversible perturbation of intracellular biochemistry with subcellular resolution. We have developed optogenetic tools based on controlling the activity of endogenous RhoA to upregulate or downregulate cell contractility. We have shown that these tools enable rapid, local and reversible changes in traction forces, cell–cell forces, and tissue compaction. We have shown, further, that changes in cellular forces are paralleled by translocation of the transcriptional regulator YAP, indicating that our tools can be used to control mechanotransductory pathways.
Collective durotaxis: a mechanism for cellular guidance by mechanical cues
Directed cell migration is one of the earliest observations in cell biology, dating back to the late XIX century. Also known as taxis, directed cell migration has been commonly associated with chemotaxis, i.e. the ability of a broad variety of cell types to migrate following gradients of chemical factors. We recently demonstrated a new mode of collective cell guidance by mechanical cues, called collective durotaxis. This new migration mode emerges only in cell collectives and, strikingly, does not require isolated cells to exhibit gradient sensing. To study the mechanisms behind this phenomenon, we developed new tools to measure the forces that propel cells during durotaxis at the cell-matrix and cell-cell levels. Upon combining this new experimental technique with biochemical approaches and theoretical modelling, we concluded that collective durotaxis originates from long-range transmission of contractile intercellular forces. This mechanism is unique in that the very same machinery that senses the attractant -the actomyosin cytoskeleton- is responsible for propulsion towards it. As such, collective durotaxis appears to be the simplest and perhaps most primitive mechanism by which a collective system responds to a gradient.
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 morphogenesis and 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”.

Researchers at IBEC and MIT have shown that cells could use their environment to mechanically communicate with each other within tissues. It’s a bit like when an army cadet pulls some rope netting taut so that his friend can safely ascend.

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.

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.
