Project description
An innovative model of tumour fibrosis
Cancer cells exist in a complex microenvironment composed of extracellular matrix (ECM), vascular, stromal and immune cells. Emerging evidence indicates that ECM remodelling causes fibrosis and tumour stiffening, the degree of which is associated with tumour aggressiveness and treatment resistance. Funded by the European Research Council, the project BEACONSANDEGG aims to develop a model of breast cancer progression that reproduces the tumour fibrosis and vascularisation. Researchers will employ a polymeric scaffold with cancer cells to recreate the human tumour microenvironment in vitro and implant it in vivo into an avian embryo to elicit fibrosis. The project will provide unprecedented information on the mechanisms of tumour fibrosis and their impact on the efficacy of therapeutic agents.
Objective
Invasive cancers are a leading cause of death worldwide, with almost ten million deaths per year caused by resistance to antitumor treatments. In breast cancer, aggressiveness correlates with fibrotic stiffening of the tumour. There is an urgent need to understand how the fibrotic microenvironment evolves, to design better targeted cancer therapies. Fibrotic stiffening is caused by fibroblasts secretion of a matrix with mechanical properties that stabilise the tumour vascular network. However, the hierarchy and stability of the tumour vascular network are not reproducible in vitro. To advance the field, I will develop a revolutionary platform able to recapitulate tumour fibrosis by exploiting the vascularisation of a living organism.
To achieve my goal, I will use human breast cancer cells adhering to 3D polymeric micro scaffolds to create arrays of tumour micro environments. I will implant the arrays in vivo in the chorioallantoic membrane of an embryonated avian egg, to elicit a foreign-body fibrotic reaction. I will vary the micro scaffolds geometry to condition tumour infiltration by the hosts vessels and cells. I will exploit fluorescent spatial beacons incorporated in the micro scaffolds for multiphoton image correlation, to derive morphological and functional information of the regenerated fibrous matrix and vessels. I will predict mass transport of solutes and anticancer agents by computational modelling. To validate the platform, I will quantify in vivo the dose-dependent efficacy and cancer specificity of therapeutic agents whose success is known to depend on the fibrotic stage of tumours.
This project combines mechanobiology to bioengineering, biomechanics, oncology, genetics, microtechnology, intravital imaging, biophysics and pharmacology to understand the progression mechanisms of the most incurable cancers. It will also provide an ethical and standardizable testing platform to boost the clinical translation of new therapeutic products in oncology.
