Purpose: Exosomes and other extracellular vesicles (EVs) have emerged as an important mechanism of cell-to-cell communication. In this work, we present a novel next generation of sequencing (NGS) based approach to identify EV mediated mRNA exchanges between co-cultured adipocyte and macrophage cells.;	Methods:We performed molecular and genomic profiling and jointly considered data from RNA sequencing (RNA-seq) and genotyping to track the sequence varying mRNAs transferred between cells.;	Results: We identified 8 mRNAs being transferred from macrophages to adipocytes and 21 mRNAs being transferred in the opposite direction. These mRNAs represented biological functions including extracellular matrix, cell adhesion, glycoprotein, and signal peptides.;	Conclusions: Our study sheds new light on EV mediated RNA communications between adipocyte and macrophage cells, which may play a significant role in developing insulin resistance in diabetic patients. This work establishes a new method that is widely applicable to examining genetic material exchanges in many other cellular systems.
