Project description:Macrophages are involved in a large number of tissue functions in homeostasis and various pathological situations. These cells present a high degree of phenotypic plasticity that is grasped by the concept of polarization. One goal of the macrophage’s biology field is to obtain molecular signatures of these polarizations. To achieve this task, it is necessary to integrate how physical environment signals are interpreted by macrophages under immune stimulation. In this work, we have studied how a 3D collagen scaffold modulates the polarizations of human macrophages and revealed that some traditionally used markers should be reassessed.To perform this task we conducted a RNAseq analysis.
Project description:The aim of this study was to conduct a comparative analysis between the AT-macrophages derived from 3D cultures and in vivo sc-AT macrophage populations. To this end, bulk RNA Seq analysis was performed between these two populations, and compared to BM- cultured macrophages. scAT macrophages were sorted based on CD45+, F4/80+ and CD11b+. AT-macrophages derived from 3D cultures and BM- cultured macrophages were harvested after 13 days in culture.
