Back from an inspiring Kick-Off Meeting in Genova! Glad to be part of the FET-Open B2B project, aiming to generate a first-of-a-kind 3D model of spontaneous breast cancer metastasis to the bone, to dissect the complexity of the metastatic process and empower high-throughput drug screening in a physiological context. A breakthrough approach to investigate metastasis longitudinally and at the single cell level!
