The effect of MSR1 knockout in macrophages in a co-culture system with BMSCs

ABSTRACT: To investigate the altered gene expression levels in MSR1 knockout and wild type macrophages in co-culture with BMSCs. Each group had a biological repeat (n=3). Results provide insight into the role of MSR1 in macrophages in a co-culture system.

Project description:Molecular mechanisms of the cancer cells-macrophages interactions growing in vitro conditions as a co-culture. The five canine mammary cancer cell lines were cultured with monocytes sorted from the canine blood for 72hrs. Then, the cancer cells and macrophages were sorted and the gene expression analysis was conducted. The control for each co-cultured cell line was the same cell line growing as a single culture, whereas the control for the macrophages growing in a co-culture conditions were macrophages growing as a single culture. Solid tumors are comprised of various cells, like cancer cells, resident stromal cells, migratory hemopoietic cells and so on. These cells regulate tumor growth and metastasis. Macrophages are probably the most important element of the interactions within the tumor microenvironment. However, the molecular mechanism how the tumor environment can educate tumor-associated macrophages (TAMs) toward a tumor-promoting phenotype still remains unknown. Moreover, there are no information how the presence of macrophages change the cancer cells phenotype. Exploring the underlying molecular mechanisms of these phenomena was the aim of this study.
