简介：
Overview
This study presents a comprehensive protocol for the isolation of primary human blood monocytes and their differentiation into macrophages and dendritic cells, which are then assembled with epithelial cells to form a multicellular human lung model. The biological responses of these cocultures, derived from both freshly isolated and thawed monocytes, are evaluated upon exposure to proinflammatory stimuli.
