About

Almost 85% of new therapeutic molecules are abandoned before the clinical trial stage. Most of these failures currently concern cancer therapies.

In order to optimize the development of these molecules and allow the development of precision medicine, an innovative screening device that is as close as possible to in vivo is necessary.

For this reason, the platform the investigators are setting up takes into account tumor vascularization as well as the 3D microenvironment.

The platform the investigators intend to set up is based on 4 cornerstones:

• the formation of patient-derived organoids seems to be the best option to take into account the microenvironment and cellular interactions.
• the vascular network: the formation of a peri-tumoral vascular network, either by using HUVECS cells or by using endothelial cells from the patient.
• the extracellular matrix, and the set of proteins it contains, is a major element of in vivo interaction. Moreover, the presence of a matrix is a key element for the development of vascularization in vitro.
• Functional tumor microenvironment: peri-tumor vascularization is necessary but not sufficient to claim to recreate a tumor microenvironment. It must be functionalized, and this implies the use of a microfluidic system.

This ready-to-use platform will be used on tumor biopsies of the patient, to constitute a tool for personalized medicine. This could even be a future component of decision at multidisciplinary board meetings.

The main objective of our research is the constitution of organoids derived from the patient in order to select, via a screening device, the best anti-tumor therapy to administer to the patient.

A secondary objective is to collect lymphocytes from the patient's blood in order to test the effectiveness of therapies mediated by the immune system (immunotherapy).
