EV-SAT: Investigating the Effects of Low Earth Orbit on Engineered Extracellular Vesicles for Advanced Therapeutic Applications
The EV-SAT mission, accepted by FALAK Astronomy Institute for Space Science, represents a pioneering step in exploring how space environments can transform next-generation therapeutics. This project focuses on immune cell-derived extracellular vesicles (EVs), nano-sized, biological particles that play a critical role in intercellular communication and are rapidly emerging as powerful, cell-free delivery systems for precision medicine.
In this mission, engineered EVs will be sent to low Earth orbit to assess how microgravity, radiation, and extreme environmental conditions influence their structure, stability, and functional properties. These unique stressors may induce beneficial modifications that are difficult or impossible to replicate on Earth, potentially enhancing EV targeting, cargo delivery efficiency, and therapeutic potency.
This work is conducted in collaboration with UCL Engineering and Princess Nourah bint Abdulrahman University, bringing together expertise in bioengineering, immunology, and translational science. Following the mission, a comprehensive suite of analytical tests will be performed to characterise EVs pre- and post-flight. These include nanoparticle tracking analysis (NTA) for size distribution and concentration, transmission electron microscopy (TEM) for morphology, proteomic and RNA sequencing for cargo profiling, and flow cytometry-based functional assays to assess uptake and immune cell modulation.
A key objective is to evaluate how space-conditioned EVs interact with immune cells, with the aim of enhancing anti-cancer responses. In parallel, we will explore the loading of EVs with therapeutic payloads such as RNA, proteins, and small molecules to determine how space exposure impacts delivery performance and biological activity.
The EV-SAT mission positions A Biotech Company at the intersection of space biology and translational medicine. By leveraging the unique conditions of space, we aim to uncover new design principles for EV-based therapeutics, accelerating the development of innovative treatments for cancer and other complex diseases on Earth.
