The tumour microenvironment conferred by mesenchymal stem cells (MSCs) plays a key role in tumour development and progression. We previously determined that platelet-activating factor receptor (PAFR) was overexpressed in ovarian cancer cells (OCCs) and that PAF can promote ovarian cancer progression via PAF/PAFRmediated inflammatory signalling pathways. | Human mesenchymal stem cells in the tumour microenvironment promote ovarian cancer progression The role of platelet-activating factor
