<meta name="description" content="Ultrasound is the most widely used imaging modality (1) and its role in noninvasive molecular imaging is expanding with ligand-carrying microbubbles (MBs) (2). MBs are composed of spherical cavities filled by a gas encapsulated in a shell. The shells are made of phospholipids, surfactant, denatured human serum albumin, or synthetic polymer. Ligands and antibodies can be incorporated into the shell surface of MBs. MBs are usually 1–8 μm in diameter, and they provide a strongly reflective interface and resonate to ultrasound waves. MBs are used as ultrasound contrast agents in imaging of inflammation, angiogenesis, intravascular thrombus, and tumors (3-5). They also have the potential to be used for drug and gene delivery (6).">

MBs are composed of spherical cavities filled by a gas encapsulated in a shell. The shells are made of phospholipids, surfactant, denatured human serum albumin, or synthetic polymer. Ligands and antibodies can be incorporated into the shell surface of MBs. MBs are usually 1–8 μm in diameter, and they provide a strongly reflective interface and resonate to ultrasound waves. MBs are used as ultrasound contrast agents in imaging of inflammation, angiogenesis, intravascular thrombus, and tumors (<a class="bibr" href="#scVEGF-MB.REF.3" rid="scVEGF-MB.REF.3 scVEGF-MB.REF.4 scVEGF-MB.REF.5">3-5</a>). They also have the potential to be used for drug and gene delivery (<a class="bibr" href="#scVEGF-MB.REF.6" rid="scVEGF-MB.REF.6">6</a>).</p><p>Vascular endothelial growth factor (VEGF) consists of at least six isoforms with various numbers of amino acids (121, 145, 165, 183, 189, and 206 amino acids) produced through alternative splicing (<a class="bibr" href="#scVEGF-MB.REF.7" rid="scVEGF-MB.REF.7">7</a>). VEGF<sub>121</sub>, VEGF<sub>165</sub>, and VEGF<sub>189</sub> are the forms secreted by most cell types, and they are active as homodimers linked by disulfide bonds. VEGF<sub>121</sub> does not bind to heparin like the other VEGF species (<a class="bibr" href="#scVEGF-MB.REF.8" rid="scVEGF-MB.REF.8">8</a>). VEGF is a potent angiogenic factor that induces proliferation, sprouting, migration, and tube formation of endothelial cells. There are three high-affinity tyrosine kinase VEGF receptors (VEGFRs) on endothelial cells (VEGFR-1, Flt-1; VEGFR-2, KDR/Flt-1; and VEGFR-3, Flt-4). Several types of non-endothelial cells, such as hematopoietic stem cells, melanoma cells, monocytes, osteoblasts, and pancreatic β cells, also express VEGFRs (<a class="bibr" href="#scVEGF-MB.REF.7" rid="scVEGF-MB.REF.7">7</a>).</p><p>VEGFRs have been found to be overexpressed in various tumor cells and tumor-associated endothelial cells but are not detectable in quiescent endothelial cells (<a class="bibr" href="#scVEGF-MB.REF.9" rid="scVEGF-MB.REF.9">9</a>). Inhibition of VEGFR function has been shown to inhibit pathological angiogenesis as well as tumor growth and metastasis (<a class="bibr" href="#scVEGF-MB.REF.10" rid="scVEGF-MB.REF.10 scVEGF-MB.REF.11">10, 11</a>). Radiolabeled VEGF has been developed as a tracer for imaging solid tumors and angiogenesis in humans (<a class="bibr" href="#scVEGF-MB.REF.12" rid="scVEGF-MB.REF.12 scVEGF-MB.REF.13 scVEGF-MB.REF.14">12-14</a>). MBs conjugated to either peptides or antibodies against integrins, cell adhesion molecules, and VEGFRs have previously been studied for the non-invasive assessment and imaging of tumor angiogenesis (<a class="bibr" href="#scVEGF-MB.REF.15" rid="scVEGF-MB.REF.15 scVEGF-MB.REF.16 scVEGF-MB.REF.17 scVEGF-MB.REF.18">15-18</a>). A 15-amino-acid long fusion tag (Cys-tag) was developed for site-specific conjugation <i>via</i> the free sulfhydryl group of Cys. Backer et al. (<a class="bibr" href="#scVEGF-MB.REF.19" rid="scVEGF-MB.REF.19">19</a>) prepared a Cys-tagged vector of VEGF<sub>121</sub> by cloning two single-chain 3–112 amino acid fragments of VEGF<sub>121</sub> joining head-to-tail to express as scVEGF, which binds to VEGFR-2. In this chapter, Anderson et al. (<a class="bibr" href="#scVEGF-MB.REF.20" rid="scVEGF-MB.REF.20">20</a>) studied ultrasonic imaging of tumor vasculature using MBs conjugated with scVEGF (scVEGF-MBs) in mice bearing human tumor xenografts.</p><div id="scVEGF-MB.Related_Resource_Links"><h3>Related Resource Links:</h3><ul><li class="half_rhythm"><div>Chapters in MICAD (<a href="/sites/entrez?Db=books&Cmd=DetailsSearch&Term=VEGFR+AND+micad%5Bbook%5D" ref="pagearea=body&targetsite=external&targetcat=link&targettype=uri">VEGFR</a>)</div></li><li class="half_rhythm"><div>Gene information in NCBI (<a href="/sites/entrez?Db=gene&Cmd=DetailsSearch&Term=3791" ref="pagearea=body&targetsite=external&targetcat=link&targettype=uri">VEGFR</a>)</div></li><li class="half_rhythm"><div>Articles in Online Mendelian Inheritance in Man (OMIM) (<a href="/sites/entrez?Db=omim&Cmd=DetailsSearch&Term=VEGFR" ref="pagearea=body&targetsite=external&targetcat=link&targettype=uri">VEGFR</a>)</div></li><li class="half_rhythm"><div>Clinical trials (<a href="http://www.clinicaltrials.gov/ct2/results?term=VEGFR" ref="pagearea=body&targetsite=external&targetcat=link&targettype=uri">VEGFR</a>)</div></li><li class="half_rhythm"><div>FDA Drug information (<a href="http://google2.fda.gov/search?q=VEGFR&client=FDAgov&site=FDAgov&lr=&proxystylesheet=FDAgov&output=xml_no_dtd&getfields=*&x=12&y=7" ref="pagearea=body&targetsite=external&targetcat=link&targettype=uri">VEGFR</a>)</div></li></ul></div></div><div id="scVEGF-MB.Synthesis"><h2 id="_scVEGF-MB_Synthesis_">Synthesis</h2><p>[<a href="/sites/entrez?Db=pubmed&Cmd=DetailsSearch&Term=scVEGF%20MB+synthesis" ref="pagearea=body&targetsite=external&targetcat=link&targettype=uri">PubMed</a>]</p><p>Backer et al.
