Last 5th-10th May was held the 2019 Gordon Research Conference on “Fibronectin, Integrins and Related Molecules” where Pere Roca-Cusachs from IBEC and Antoine Khalil from UMCU presented talks discussing Mechanocontrol results on how mechanical signals and the extracellular matrix regulate cell responses and tumour invasion. During the keynote session titled “Mechanisms and Mechanics of Integrin ECM Connections” Pere Roca-Cusachs gave a talk on “Exploring the Substrate Dependence of Integrin-Mediated Mechanotransduction”. Antoine gave an oral presentation where he described how cell-ECM adhesion regulates the positioning of basal cells and their specification into invasive leader cells during collective invasion of breast cancer organoids.
The Gordon Research Conference was held in Lucca, Italy and is the premier international conference for academic, government and industry scientists interested in understanding how integrins and the extracellular matrix regulate virtually every aspect of cell and tissue function. The program of the conference reflected the interdisciplinary nature of the integrin and extracellular matrix field, spanning different areas of biology from inflammation to mechanobiology, cell migration, stem cells, development, and cancer. During the meeting unpublished data was highlighted and stimulated active discussion among all participants.
The application period opens today until the 8th May 2019, where you can submint an abstract if you are interested in giving a short talk during the summer school.
The application does not guarantee acceptance to the Summer School due to the limited number of participants, an email with the resolution of the applicaton process will be sent on June 15th 2019.
The summer school will be held in La Cerdanya at the Eco-Resort located in Prullans in the Catalan Pyrenees.
The participation fee is 300€ (taxes not included) and includes accomodation in shared double room (from 17th-20th September 2019), full-board, workshops and conferences, leisure activities and shuttle bus from Barcelona to the venue.
hosting two members from the Mechano·Control network. On the one hand, Dimitri
Kaurin, PhD student from Marino Arroyo group at Universitat Politècnica de
Catalunya (UPC) that will be staying at IBEC for at least one year and on the
other hand, Amy Beedle, postdoc from Sergi Garcia-Manyes at Kings College
Dimitri Kaurin started his stay at Pere Roca-Cusachs’ laboratory in December 2018 and it is planned to be for at least a year. One of the objectives of Dimitri’s stay is to work on a protocol to study cell-cell adhesion using a controlled system based on lipid bilayers of controlled viscosity. “Using AFM technique, we expect to access some information about cell-cell adhesion under force” says Dimitri. In the context of this research he will also visit Manuel Salmeron laboratory in Glasgow University this march to learn some techniques about functionalizing lipid bilayers with cadherins.
On the other hand, Amy Beedle arrived this past January to Pere Roca-Cusachs’ laboratory. In the Garcia-Manyes lab Amy was looking at how mechanical forces can trigger conformational changes in individual proteins. Here at IBEC, she wants to incorporate the results at the single molecule level with the cellular level, to try to understand how individual bonds and proteins can contribute to cellular mechanosensing. “My aim is to expand my expertise in single molecule force spectroscopy to a larger cellular context” adds Amy.
This is the first time that both UPC and KCL teams meet with IBEC to share skills and ideas within the project’s framework.

consortium, led by several research institutions across Europe, is launching a
Summer School that will be taking place between 17-20 of September 2019 at the
Eco Resort in La Cerdanya. The aim of the summer school is to provide training
on mechanobiology, and specifically its application to breast cancer.
This school will include lectures as well as practical workshops in different
techniques and disciplines, ranging from modelling to biomechanics to cancer
There will be scientific sessions in the morning, mixing 6
keynote speakers with 18 short talks selected from abstract submissions by
junior scientists attending the school. In the afternoon, there will be 2-3-hour
practical workshops, given by scientists from the MECHANO·CONTROL consortium.
The course will also include leisure activities.

TheMECHANO·CONTROL project is focused on the mechanical control of biological function.Mechanical forces transmitted through specific molecular bonds drive biological function, and their understanding and control holds an uncharted potential in oncology, regenerative medicine and biomaterial design.
MECHANO·CONTROL proposes to address
this challenge by building an interdisciplinary research community with the aim
of understanding and controlling cellular mechanics from the molecular to the
organism scale. At all stages and scales of the project, it will integrate
experimental data with multi-scale computational modelling to establish the
rules driving biological response to mechanics and adhesion. With this
approach, it aims to explore novel therapeutic approaches beyond the current
paradigm in breast cancer treatment. If the partners can understand cancer
biomechanics from the single molecule to the whole organ scale, they’ll be able
to control mechanical forces to restore healthy cell behaviour and inhibit
Beyond breast cancer, the general principles targeted with this technology will have high applicability in oncology, regenerative medicine, biomaterials and many other biological processes and diseases.
MECHANO·CONTROL is a project funded
by the European Commission, within the Future and Emerging Technologies (FET)
A review article by Antoine A. Khalil and Johan de Rooij from UMC Utrecht have appeared in the Experimental Cell Research section of Elsevier
Collective invasion drives the spread of multicellular cancer groups, into the normal tissue surrounding several epithelial tumors. Collective invasion recapitulates various aspects of the multicellular organization and collective migration that take place during normal development and repair. Collective migration starts with the specification of leader cells in which a polarized, migratory phenotype is established.
Leader cells initiate and organize the migration of follower cells, to allow the group of cells to move as a cohesive and polarized unit. Leader-follower specification is essential for coordinated and directional collective movement. Forces exerted by cohesive cells represent key signals that dictate multicellular coordination and directionality. Physical forces originate from the contraction of the actomyosin cytoskeleton, which is linked between cells via cadherin-based cell-cell junctions.
The cadherin complex senses and transduces fluctuations in forces into biochemical signals that regulate processes like cell proliferation, motility and polarity. With cadherin junctions being maintained in most collective movements the cadherin complex is ideally positioned to integrate mechanical information into the organization of collective cell migration. Here we discuss the potential roles of cadherin mechanotransduction in the diverse aspects of leader versus follower cell specification during collective migration and neoplastic invasion.
The biotechnology company Iproteos, IBEC and the Vall d’Hebron Research Institute (VHIR) are set to develop an innovative treatment to slow down, stop and even reverse the growth of solid tumors, which represent more than 90% of cancer cases.
It’s a family of peptidomimetic drugs based on a totally new anti-tumor action mechanism, the result of several years of research by Pere Roca-Cusachs’ group at IBEC.
An opinion piece by IBEC group leader Xavier Trepat has appeared in the News and Views section of the current issue of Nature, which is devoted to ‘Bottom-up biology’.
In his piece ‘Bottom does not explain top’, Xavier argues that understanding how complex biological structures – or even entire cells – are built can only provide a certain amount of insight into how biological systems function at higher levels of organization. There are many variables such as density, or even pathologies suffered by the subject, that affect cell behavior at the mesoscale – that is, at the longer, more ‘system-level’ scale than that of the individual components of an organism. Cells in a group, for example, can sense or respond to external stimuli that an individual cell cannot identify.
Mechano·Control is holding its third consortium meeting today at University Medical Center Utrecht.
Representatives from all seven partners – the UPC and Mind the Byte S.L. in Spain, UMC Utrecht and Noviocell B.V in the Netherlands, Germany’s Leibniz-Institut, and King’s College London – have gathered in the Netherlands for the meeting, which will present and discuss the state of the work packages and results so far.
During the meeting, issues related to the dissemination and exploitation of the project will also be reviewed.
One of the most enviable features of superheroes is their ability to stretch their bodies beyond imaginable limits. In a study published in Nature, scientists have discovered that our cells can do just that.
With every beat of the heart and every breath into the lungs, cells in our body are routinely subjected to extreme stretching. This stretching is even more pronounced when cells shape our organs at the embryo stage, and when they invade tissues through narrow pores during cancer metastasis – but how cells undergo such large deformations without breaking has remained a mystery until now.
This week, researchers at IBEC and the UPC report a new physical property of cells – which they’re calling active superelasticity – that may explain the unusual ability of cells to undergo extreme deformations.
The team, led by Marino Arroyo and Xavier Trepat (centre and right), developed a new approach to subject epithelial tissues – the thin cellular layers that cover internal and external surfaces of the body – to very large deformations, up to four times their original size. These cellular layers 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.
