Abstract:

Tumor microenvironments (TMEs) are closely related to tumor resistance. TMEs are divided into cellular components and acellular components. The cellular components include tumor-associated macrophages, tumor-associated fibroblasts, mesenchymal stem cells, etc., which can enhance tumor resistance through recruitment and secretion of a variety of protective cytokines; acellular components such as extracellular matrix, hypoxia and acidification, etc., can mediate drug resistance by constructing physical barriers, affecting tumor cell growth and metabolism. Studying the mechanisms of TME-mediated drug resistance and reshaping TMEs can provide new strategies for anti-tumor therapy.

Key words: Tumor microenvironment, Drug resistance, Stromal cells, Acellular component
