Karina Yaniv
Karina Yaniv is an Israeli scientist who is best known for her contributions to the field of vascular development. She is a Professor of Vascular Disease in the Department of Biological Regulation at the Weizman Institute of science, Rehovot, Israel. She has three kids: Yotam Yaniv, Nitay Yaniv, and Eylon Yaniv, and since 2023 is married to another Weizmann Institute of Science biologist, Eldad Tzahor.
Research
Yaniv investigates the mechanisms that regulate blood and lymphatic vessel formation during embryonic development and in disease. She utilizes zebrafish embryos to study the mechanisms controlling the lineage specification of lymphatic endothelial cells and the development of lymphatic vessels.A recent achievement was the discovery of a new niche of specialized progenitors which gives rise to the lymphatic system. They identified the first "lymphatic-inducing" signal, capable of inducing lymphatic differentiation of human embryonic stem cells. Her laboratory generated for the first time human lymphatic endothelial cells in culture, which opens the way for other laboratories to understand the basic determinants and behavioral properties of these cells.
Research in Yaniv's laboratory also focuses on lymphatic vessels in the heart: how do they form and what is their possible role in heart diseases. Other projects focus on the mechanisms that control the formation of lymphatic vessels induced by tumors, since the lymphatic system is the key route for dissemination of metastatic cells.
