Abstract: Breast cancer is a heterogeneous systemic disease.Its microenvironment is mainly composed of tumor cells and a variety of non-tumor cells.Among them,mesenchymal stem cells(MSCs)play an important role in tumorigenesis and development.MSCs can interact with tumor cells and their microenvironment directly through gap junctions,membrane receptors and microtubules,or indirectly through soluble molecules.Tumor-associated fibroblasts(CAFs)are derived from adjacent cancer fibroblasts or MSCs,and play an important role in tumor drug resistance.In breast cancer,tumor stem cells and their microenvironment are in a dynamic equilibrium state,and their phenotype is closely regulated by cytokines.Interstitial cells have an important effect on their biological characteristics through their interaction with breast cancer cells.In addition,interstitial cells can change the sensitivity of tumor cells to chemotherapeutic drugs,which in turn make them resistant.Therefore,addressing tumor stromal cell-mediated resistance to chemotherapy is the key to successful treatment of advanced breast cancer.This article mainly describes the research progress of stromal cells in the microenvironment mediated chemotherapy resistance of breast cancer.
