A Robust In Vitro Co-culture Model for Studying the Intercellular Communication of Neutrophils.

Abstract

Communication among neutrophils plays critical roles during various phases of inflammatory responses, with clinical relevance to both acute and chronic inflammatory diseases. Despite its significance, underlying mechanisms are not well understood, due to the lack of an effective in vitro system to properly address this important question. Here we report a robust in vitro method to culture primary murine neutrophils derived from bone marrow, amenable for well-controlled studies of both neutrophil activation and intercellular communication among co-cultured neutrophils. This protocol can generate primary neutrophils with high purity and survival for an extended culture period, suitable for further phenotypic and functional analyses.
