Cancer cells undergo unlimited progression and survival owing to activation of
oncogenes. However, support of the tumor microenvironment is essential to the
formation of clinically relevant tumors. Recent evidence indicates that the tumor
microenvironment is a critical regulator of immune escape, progression, and
distant metastasis of cancer. Moreover, the tumor microenvironment is known to be
involved in acquired resistance of tumors to various therapies. Despite
significant advances in chemotherapy and radiotherapy, occurrence of therapeutic
resistance leads to reduced efficacy. This review highlights myeloid cells,
cancer-associated fibroblasts, and mesenchymal stem cells consisting of the tumor
microenvironment, as well as the relevant signaling pathways that eventually
render cancer cells to be therapeutically resistant.
