Vasculogenesis and angiogenesis in the iugr placenta juan a. Vasculogenesis and angiogenesis during development and differentiation. Vasculogenesis gives rise to the heart and the first primitive vascular plexus inside the embryo and in its surrounding membranes, as the yolk sac circulation. On the other hand, intussusceptive angiogenesis involves formation of blood vessels by a splitting process in which elements of interstitial tissues invade existing vessels, forming transvascular tissue pillars that expand. Endothelial and smooth muscle cells interact with each other to form new blood vessels. Isbn 9789533078823, pdf isbn 9789535167471, published 20111107 vasculogenesis is the process of new blood vessel formation during embryonic development of the cardiovascular system.

The mesodermal progenitor cells derived from embryonic stem cells esc differentiate in. Angiogenesis is the growth most often associated with damaged or smaller blood vessels, while vasculogenesis generally occurs when the primary blood system is being created or changed. Angiogenesis has essential roles in development, reproduction and repair but also occurs in tumor formation and in a variety of diseases 1, 2. Abstract angiogenesis is a process that involves the.

This is followed by formation of a vascular tree and finally the cardiovascular system with the myriad of blood vessels that nourish all tissues and organs. Two distinct mechanisms, vasculogenesis and angiogenesis implement the formation of the vascular network in the embryo. Both types of angiogenesis are thought to occur in virtually all tissues and organs.
Our lab studies the angiogenic process by computational modeling across multiple scales 3, 4 and by in vitro microfluidic experiments that mimics in vivo biophysical. Wnt signaling pathway and its role in cancer and patterning of the brain duration. In this video we discuss an overview of the two types of angiogenesis, namely sprouting angiogenesis and intussusceptive angiogenesis.
