Here, we present an integrated workflow to identify phenotypic and molecular features that characterize circulating tumor cells (CTCs). We combine live immunostaining and robotic micromanipulation of single and clustered CTCs with single cell-based techniques for downstream analysis and assessment of metastasis-seeding ability.
FAQs
Metastatic spread depends on a sequence of successful transitions rather than a single event. Cells must invade locally, enter blood or lymphatic vessels, remain viable during circulation, exit into another tissue, and establish a secondary tumor. Failure at any stage can limit dissemination, so cancer research examines the process as a coordinated series of biological challenges.
After entering blood or lymphatic vessels, cancer cells must withstand transit long enough to reach a distant tissue. Circulating survival therefore connects local invasion with later tissue colonization. Studying this stage helps distinguish cells that merely leave a primary tumor from those capable of completing dissemination and contributing to secondary tumor formation.
Metastatic potential serves as an indicator of how effectively tumor cells can complete the steps required for distant spread. A tumor with greater capacity for invasion, circulation, tissue exit, and colonization may be considered more aggressive. In cancer research, this relationship makes metastatic potential useful for characterizing disease severity and interpreting differences among tumors.
Researchers evaluate metastatic potential by examining whether cancer cells can carry out the major stages of dissemination, including local invasion, vascular entry, survival during circulation, exit into a new tissue, and colonization. Experimental models can organize these observations and help characterize tumor behavior, compare aggressiveness, and investigate where metastatic progression succeeds or fails.
Because metastatic potential relates to tumor aggressiveness and disease severity, its evaluation can help identify biomarkers associated with likely clinical outcomes. Researchers can compare metastatic behavior with indicators of tumor progression to assess whether particular biomarkers reflect dissemination capacity. This work supports the search for markers that help characterize cancer and inform prognosis.
Therapy studies use metastatic potential to investigate whether an intervention can interrupt one or more stages of dissemination. Evaluations may focus on local invasion, vascular entry, survival in circulation, tissue exit, or secondary-site colonization. Linking treatment effects to these stages helps researchers determine how an experimental therapy influences metastatic progression, a major challenge in cancer treatment.
