Signaling between cancer cells, their neighboring cells, and mesenchymal stem cells (MSCs) forms the tumor microenvironment. The complex heterogeneity of this microenvironment varies depending on the tumor type and its origins. However, most of the existing cancer-based studies have focused on cancer cells. In this study, we used a direct co-culture system (cross-talk signaling) to induce cross-interaction between cancer cells and mesenchymal stem cells. This induced deformation of MSCs. MSCs showed a diminished ability to maintain homeostasis. In particular, increase in the invasion ability of MSCs by TGF-β1 and decrease in p53, which plays a key role in cancer development, is an important discovery. It can thus be deduced that blocking these changes can effectively inhibit metastatic colorectal cancer. In conclusion, understanding the interactions and changes in MSCs associated with cancer will help develop novel therapeutic strategies for cancer.
