N2 - The integration of artificial and mammalian cells into semi-synthetic aggregates remains a challenge in bottom-up synthetic biology. Here, the fabrication of cell membrane vesicles (CMV) from HepG2 cells and their use as a coating for alginate microgels to produce camouflaged artificial cells (ACs) is demonstrated. These ACs are used for the assembly of either synthetic aggregates or semi-synthetic aggregates. In the first case, a predator-defendant and a liver-like synthetic aggregates are investigated, showing promising initial steps toward complex synthetic aggregates. In the other case, the camouflaged ACs show enhanced integration with HepG2 cells. The encapsulation of a reactive oxygen species (ROS) scavenger artificial enzyme in the ACs shows protection against tert-butyl hydroperoxide in terms of HepG2 cell viability, proliferation, and mitochondrial health in semi-synthetic aggregates. Taken together, this effort is a substantial step forward in combining mammalian cells and ACs in the same aggregate where the latter act as support units.
