Microgravity for Personalized Medicine (M4PM) is a programme focused on 3D Tumour, Organoid and Spheroid growth in microgravity to enable the development of space-based Personalised Medicine. Set out under a partnership between Blue Horizon and Space Applications Services, and co-financed by the European Space Agency, the project aims to create both a technical model as well as a business model that replicates and enhances traditional terrestrial ones.
