ABSTRACT
When tumor cells are released from a primary tumor into the bloodstream or lymphatic circulation system, they are exposed to a continuous shear flow environment. This environment exerts physical stresses on the tumor cells, which can activate apoptotic pathways. However, certain tumor cells have the ability to adapt to these mechanical stresses, enhancing their likelihood of survival and promoting metastasis. In this study, these tumor cells survived from shear flow environment are examined and revealed to closely link to stem cell-like characteristics. Higher gene expression levels of self-renewal and differentiation markers and enhanced abilities of migration, spheroid formation, and colony formation are shown. Moreover, the interaction between immune cells and the surviving cells is investigated. The results show that the surviving cells possess immune escape capabilities, implying their ability to evade immune surveillance. Additionally, these surviving cells display characteristics reminiscent of stem cells. This study holds great importance in advancing the understanding of tumor biology. By comprehending the behavior and properties of these surviving cells, new therapeutic strategies can be developed to specifically target circulating tumor cells (CTCs) and enhance cancer treatment outcomes.
