It is a well-characterized inhibitor of several mesodermal differentiation pathways. sDLK-1 functions as an endocrine signaling molecule, particularly during periods of high metabolic demand like pregnancy or early development. Unlike its typical inhibitory roles, soluble DLK-1 has been shown to stimulate angiogenesis (the formation of new blood vessels) by activating Notch1\/Akt signaling in endothelial cells. In certain contexts, such as pancreatic cancer models, sDLK-1 exhibits antitumor effects by suppressing cell migration, wound healing, and colony formation. Because it is highly expressed in the fetus and placenta, maternal serum levels of sDLK-1 are used as a marker for fetal growth restriction and other pregnancy complications.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30%;\" data-mce-style=\"width: 30%;\"\u003e\u003cstrong\u003eTissue Specificity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 70%;\" data-mce-style=\"width: 70%;\"\u003eExpression in the stromal cells in close contact to the vascular structure of placental villi, yolk sac, fetal liver, adrenal cortex and pancreas and in the beta cells of the islets of Langerhans in the adult pancreas.
