Developing a Microbubble-based Contrast Agent for X-ray Phase Contrast Imaging to Detect Neovasculature in Breast Cancer
X-ray phase contrast imaging (XPC) generates contrast from refraction and scattering of X-rays, unlike absorption in conventional radiology. This technique greatly improves the sharpness of boundaries and reveals micro-structured tissues that are not easily detected by conventional absorption-based …

MICRO-CT EVALUATION OF MSC/HUVEC/HSC-MEDIATED ANGIOGENESIS IN LARGE PCL-ßTCP CONSTRUCTS IMPLANTED IN NUDE MICE
… were harvested, demineralized and analyzed for neovasculature by microcomputed tomography (micro- CT). The formation of microvasculature was significantly higher in the MSC-HUVEC and MSC-HSC constructs than those seeded with MSC alone or cell-free constructs. Volumetric analysis showed that …

Heparan sulfate glycosaminoglycan regulation of vasculogenesis
… stem cells is an emerging concept to generate neovasculature. The differentiation of embryonic stem cells into endothelium has been well documented, however most studies focus on genetic or chemokine regulation. Limited information exists which implicates the role of the extracellular …

Thermoacoustic Imaging and Spectroscopy for Enhanced Cancer Diagnostics
… and monitor the size, shape, heterogeneity, and neovasculature of the tumor microenvironment during a month long study. Average volumetric growth was 5.35 mm³/day, which correlated well with two dimensional results from fluorescent imaging (R = 0.97, p < 0.01). Spectroscopic PA imaging is also …

Novel contrasts in photoacoustic tomography
… gold nanoparticles. The PA signals of neovasculature in the mouse flank were enhanced by the ___3-targeted copper nanoparticles. Moreover, the work shows the first example of a systemically targeted antiangiogenic drug delivery with a photoacoustic contrast nanoparticle in …
