Effect of 2D and 3D cell culture system on trophoblast extracellular vesicles physio-chemical characteristics and potency

In this project, trophoblast cell analogue human chorionic carcinoma cell line was cultivated in both conventional monolayer culture (2D) and as spheroids in suspension cultures (3D) and how the cell growth environment affects the physical and biochemical properties of EVs produced by them was studied. Importantly, proteomic cargo profile of EVs derived from 2D and 3D cultures was compared. There was substantial differences in the proteomic cargo profile and potency of EVs derived from two culture systems. Findings of this study will help in selecting an EV production platform, especially for assessing the functional and therapeutic potential of EVs.
