ABSTRACT
<p><b>OBJECTIVE</b>To exploration the endothelialization of prostheses with bone marrow CD(34)(+) cells.</p><p><b>METHODS</b>CD(34)(+) cells were isolated from bone marrow of carine by an immune magnetic cell sorting system and induced into endothelial cells with VEGF. Seeding the cells to PTFE prostheses which implanted the abdominal aorta artery (AAA) and inferior vena cava (IVC).</p><p><b>RESULTS</b>The isolated cells from bone marrow were CD(34)(+) by flow cytometer which could differentiate into endothelial cells in vascular endothelial growth factor (VEGF). The endothelial cells were identified by immunostaining and transmission electron microscope. The obliteration rate of the seeding grafts implanting AAA was 0%, the stenosis rate 12.5%; the obliteration rate implanting IVC 12.5%, the stenosis rate 25%.</p><p><b>CONCLUSION</b>CD(34)(+) cells were isolated from bone marrow by an immune magnetic cell sorting system and were able to be induced into endothelial cells with VEGF in vitro. PTFE prostheses seeding CD(34)(+) cells have the ideal endothelialization and patency.</p>
