The tumor microenvironment consists of stromal cells, extracellular matrix (ECM),
and signaling molecules that communicate with cancer cells. As tumors grow and
develop, the tumor microenvironment changes. In addition, the tumor
microenvironment is not only influenced by signals from tumor cells, but also
stromal components contribute to tumor progression and metastasis by affecting
cancer cell function. One of the mechanisms that cancer cells use to invade and
metastasize is mediated by actin-rich, proteolytic structures called invadopodia.
Here, we discuss how signals from the tumor environment, including growth
factors, hypoxia, pH, metabolism, and stromal cell interactions, affect the
formation and function of invadopodia to regulate cancer cell invasion and
metastasis. Understanding how the tumor microenvironment affects invadopodia
biology could aid in the development of effective therapeutics to target cancer
cell invasion and metastasis.
