Abstract
- Extracellular vesicles (EVs) play a pivotal role in cancer progression. However, the majority of functional studies performed so far relies on data acquired in traditional 2D cultures. Because the spatial architecture of tissue is decisive for the cell fate, new cell models to study EV functions in the 3D environment must approximate in vitro models to the physiological conditions. Several models were developed during the last years, which may be suitable to serve as 3D models to study EVs; among them are hydrogels, solid scaffolds, bioreactors, and 3D CoSeedis™ inserts. We present in this chapter a protocol for a 3D cell model based on the 3D CoSeedis™ agarose inserts, allowing for a long-term culture of cells of different origins under serum-free conditions and easy EV recovery. Additionally, information on individual culture conditions in 3D CoSeedis™ for different cell lines, protocols for model evaluation, and quality controls are included. We hope that our suggestions and experience will be useful to carry out EV study under more physiological conditions and contribute to the EV research field's progress.
