Endothelium and embryonic leukocyte migration

​​Description of research

The mechanisms mediating and regulating leukocyte migration through the endothelium during fetal ontogeny and the impact of the embryonic origin of cells in adults are still almost completely unknown. The objective of our research is to answer how fetal leukocytes migrate from the tissue of origin via endothelial cells to the blood vessels, and exit from blood vessels to the target tissues. We will study how fetal origins of leukocytes influence the tissue development and adult pathophysiology.
