The trajectory of tumor cells during metastasis can be influenced by many factors, including the physical environment and the genetic makeup of metastatic clones. In high-grade serous ovarian cancer, there are limited barriers in the intraperitoneal space, allowing for extensive spreading and mixing of tumor cells. A recent article published in Nature Genetics explores these different patterns of clonal evolution in metastatic ovarian cancer using a combination of bulk and single cell sequencing.  Read more
