A major advance in biological investigation models has come from our ability to cultivate complex multicellular models with associated cell diversity and higher order architecture: organoids. However, this technology raises many technological challenges. The goal of this project is to federate the research effort on organoids in the West. This project will revolve around the networking of technological core facilities in biology-health-agronomy of Biogenouest network. An identification of the strengths and needs will make it possible to establish a core facility skills development strategy to best meet the needs related to organoids.
