Fig. 3From: Crosstalk and plasticity driving between cancer-associated fibroblasts and tumor microenvironment: significance of breast cancer metastasisCommunication between breast CAFs and tumor. CAFs regulates the growth and invasion of cancer cells by secreting cytokines, exosomes, ECM and stromal cells. A The mode of action of cytokines (growth factors, chemokines, interleukins) B CAFs cut off the transfer pathway by targeting exosomes C Remodeling of the extracellular matrix D Relationship between CAFs and stromal cells (mainly macrophages)Back to article page
