Researchers have found that by helping to form clots within tumors, immune cells that flock to a particular type of lung cancer are actually building a foundation for the tumor to spread within the body. (futurity.org)
These immune cells, which normally help to build clotting scaffolds to promote wound healing, also make it possible for tumor cells to migrate and spread to other parts of the body. (futurity.org)
They produce a large amount of a factor that leads to clot in the tumor, which the tumor cells can latch onto and climb across to spread in the body," says Chad Pecot, assistant professor in the University of North Carolina's School of Medicine division of hematology/oncology and the study's corresponding author. (futurity.org)
These immune cells then release a clotting factor, Factor XIIIA, which Pecot says creates a fibrin scaffold that tumor cells climb across and then travel to distant organs. (futurity.org)
