<p class="jove_step">Procedure</p>
<ol>
<li>Lay cord on clean pad and dab off excess blood. Make fresh cuts on both ends of the cord.</li>
<li><strong>Insert 21 1/2 G needle</strong> with the plastic needle sheath ON, into the vein. (The vein is the largest opening; the 2 smaller ones are arteries)</li>
<li><strong>Clamp the needle</strong> in place with a hemostat and attach the 20cc syringe of Hanks to the needle.</li>
<li><strong>Push the Hanks through</strong> the vein with moderate pressure. Collect the waste in the beaker with bleach. (Ho...

isolation of human umbilical vein endothelial cells (huvec)

<p class="jove_content">Angiogenesis is a complex multi-step process, where in response to angiogenic stimuli, new vessels are created from the existing vasculature. These steps include: degradation of the basement membrane, proliferation and migration (sprouting) of endothelial cells (EC) into the extracellular matrix, alignment of EC into cords, lumen formation, anastomosis, and formation of a new basement membrane. Many in vitro assays have been developed to study this process, but most only mimic certain stages of angiogenesis, and morphologically the vessels often do not resemble vessels in vivo. Here we demonstrate an optimized in vitro angiogenesis assay that utilizes human umbilical vein EC and fibroblasts. This model recapitulates all of the key early stages of angiogenesis, and importantly the vessels display patent intercellular lumens surrounded by polarized EC. Vessels can be easily observed by phase-contrast and time-lapse microscopy, and recovered in pure form for downstream applications.</p>

Isolation of Human Umbilical Vein Endothelial Cells HUVEC

<p class="jove_content">This video protocol illustrates the isolation and culture of human umbilical vein endothelial cells (HUVEC) from human umbilical cord.   Once isolated these cells can be used for in vitro angiogenesis assays like the Optimized Fibrin Gel Bead Assay also demonstrated by the Hughes lab.
