Witryna3 mar 2024 · The culture medium was changed every 2–3 days until Caco-2 cells were fully differentiated into polarized monolayers. THP-1 cells were seeded in 12-well plates (2 × 10 5 cells/well) with PMA (150 ng/mL) for 48 h. After replacing the medium, inserts with Caco-2 cell monolayers were added to the plates containing THP-1 cells. portland me street maintenance
