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.
Stretching epithelial tissues
Epithelial tissues are fundamental to life, as they protect the body from radiation, pollutants and pathogens. They’re also responsible for gas exchange in the lungs, absorption of nutrients in the gut, and excretion of urine in the kidneys. We developed a new approach to subject epithelial tissues to very large deformations, up to four times their original size. Most materials are ‘unhappy’ during stretching. As they become progressively deformed, they want to go back to their unstretched state, like a rubber band, or may even break as the tension increases. We found that epithelial sheets have a different and unusual mechanical behavior. To our surprise, tissues did not break during stretching, and they were able to recover their initial size in a fully reversible way when unstretched. Even more surprisingly, some cells in the tissue barely stretched, while others became ‘superstretched’, increasing their area more than ten times. We identified the molecular mechanisms that explain this physical behavior, which we call ‘active superelasticity’ as an analogy with the behavior of some high-tech metal alloys used in medical technologies. Understanding this surprising mechanical behavior in epithelial tissues could help us build better artificial organs or new bionic technologies such as organs-on-a-chip.

A team of experts from the Institute for Bioengineering of Catalonia (IBEC) has published a review in the journal Nature Reviews Physics detailing the different techniques used to calculate mechanical stress in tissues, both in cell cultures and in vivo. Determining these mechanisms of mechanical stress is crucial to study processes linked to morphogenesis, homeostasis, and diseases such as cancer.
In order to work properly, living tissues need to continuously move, divide, reshape and perceive their microenvironment. In other words, they need to withstand certain mechanical stress derived from contact.
Xavier Trepat, group leader of the “Integrative cell and tissue dynamics” at IBEC together with Raimon Sunyer, Senior researcher in Trepat’s lab, have written a Primer in Current Biology magazine on “Durotaxis”, a cell migration mechanism that might have a role in several disease states that include the stiffening of tissues.
Embryo development, tumour progression or the immune response against pathogens requires cell migration.
The researcher at the Institute for Bioengineering of Catalonia (IBEC), Xavier Trepat, has received the prestigious ERC Advanced Grant awarded by the European Research Council (ERC) worth 2.5 million euros.
Thanks to this grant the expert and his group will be able to study the mechanical properties of the epithelium in 3D and to lay the foundations for a pioneering technology called “Epifluidics”, which will allow the design of biological robots.
Xavier Trepat reveals to the Ara journal the secret behind the famous boom challenge.
During the EMBL-IBEC Winter Conference held on February 10-12 in La Pedrera, Xavier Trepat, principal investigator at IBEC, was interviewed for the ARA newspaper.
The conference organised by the Institute for Bioengineering of Catalonia (IBEC) and the European Molecular Biology Laboratory (EMBL) brought together a total of 200 international experts in the field of bioengineering at La Pedrera building in Barcelona.
This week, the conference organised by the Institute for Bioengineering of Catalonia (IBEC) and the European Molecular Biology Laboratory (EMBL) brought together a total of 200 international experts in the field of bioengineering at La Pedrera building in Barcelona.
At the opening of the event, which was led by the mayor of Barcelona, Ada Colau, attention was drawn to Barcelona’s consolidation as an international centre of research and knowledge.
Three IBEC projects have been selected to receive funding from “La Marató 2018: Against Cancer.” One of the projects is led by the researcher Pere Roca-Cusachs and the other two are co-led by the researchers Xavier Trepat and Núria Montserrat.
The awarding ceremony took place on October 30 in the Auditorium of the Academy of Medical and Health Sciences of Catalonia and the Balearic Islands. In this edition, over the 188 evaluated projects, 43 have been selected by an international committee of experts in cancer based on their excellence, methodology and relevance. La Marató de TV3, together with Catalunya Ràdio, broadcasts its annual telethon to raise funds for scientific research into various diseases with a different theme each year.
More than 60 people attended the “Mechanobiology of Cancer Summer School 2019” organised by IBEC as the center is in charge of coordinating the Mechano·contorl project. The summer school was held in Prullans, a tiny village located at the Catalan Pyrinees between 17 and 21 of September. The event was a great success both in participation and scientific level. The aim of the summer school was to provide training on mechanobiology, and specifically its application to breast cancer, and promote interactions between professionals of the field.
The school included lectures as well as practical workshops in different techniques and disciplines, ranging from modelling to biomechanics to cancer biology. The Mechano·Control project, coordinated by Pere Roca-Cusachs, principal investigator of the IBEC is the largest European project coordinated by the IBEC to date.
