Metastasis is the leading cause of cancer deaths worldwide. However, there exist only limited treatment options and they are often ineffective. An important aspect of metastasis that requires study, but has previously been understudied is circulating tumor cells (CTCs). CTCs are a critical step in the metastatic cascade. They can be analyzed for the identification of key mechanisms in metastasis. To this end, we isolated CTCs from a syngeneic mouse model of hepatocellular carcinoma (HCC) and a human xenograft mouse model of castration-resistant prostate cancer (CRPC). From these mouse models, primary tumor and CTC lines were established. Functional characterization of …

The outer cardiac layer, the epicardium, coordinates the final steps of vertebrate heart development. This cardiac tissue arises from cells in the proepicardial organ (PEO) that forms around the base of the inflow tract. Its general location is conserved across species despite morphological differences. Cellular mechanisms of migration differ across species. Three strategies of PEO migration are described: 1) The floating cyst model - PEO cells released into the pericardial cavity are directed by fluid movements to migrate onto the myocardium; 2) Villi transfer - cardiac contractions may mediate multicellular PEO villi contact to the myocardium; and 3) Tissue bridge-mediated …
