Danger signal initiates differentiation of monocytes into osteopontin‑producing macrophages III


ABSTRACT: Purpose: We report the application of single-cell RNA sequencing for profiling the genexpression of different monocyte types in order to characterize monocytes that differentiate into macrophages under danger signal in comparison to conventional GM-CSF and M-CSF macrophages Methods: Monocytes freshly isolated from PBMCs were differentiated into GM-CSF, M-CSF, and danger-signal induced macrophages. Two million cells of each macrophage population were tagged accordingly with TotalSeq™‑B Hashtags. Single cell RNA sequencing was performed on all macrophage populations in order to characterize cells from each population. ScRNAseq analysis was performed with the R package Seurat on 16470 barcodes after filtering. Results: Cluster analysis reveals distinct separation of all three macrophage populations. Conclusion: The clear difference in overall gene expression profile suggests that macrophages exposed to danger signal differentiate into a novel macrophage type in contrast to conventional GM-CSF and M-CSF monocytes.
