Ultrasound Induced Angiogenesis

By Chenara Johnson, Graduate Student

Ischemia is the underlying pathology of many diseases which lead to poor circulation, necrosis and eventual loss of function. The progression of vascular occlusive diseases, more specifically, often result in insufficient oxygenation and claudication or critical limb ischemia (Schirmer and Royen 2004). In an effort to combat the effects of these diseases numerous attempts to induce angiogenesis and arteriogenesis, as a means of collateral blood supply, have been made. While cellular/molecular (Messina et al. 2002, Guan et al. 2007) and genetic (Jiang et al. 2007, Hung et al. 2007, Hiasa et al. 2004) endeavors continue to be pursued, these have not translated well into the clinic as apparent by the multitude of literature, but persisting complications. Ultrasound has been reviewed for its therapeutic effects since the early 1960s (Paul et al. 1960, Galitsky et al. 1964) and continues to show promise for angiogenic induction in ischemic tissues both without (Barzelai et al. 2005) and with the use of contrast agents (Song et al. 2002, Song et al. 2004, Chappell et al. 2005). Other literature combines the genetic/cellular methods with ultrasound contrast agents (UCAs) to promote the biological effect (Price et al. 1998, Zen et al. 2006, Korpanty et al. 2007, Leong-Poi et al. 2007).

While there are some central dogmas for exposure conditions to encourage collateral growth (i.e. low frequency, low pressure), the pulsing conditions, use of contrast agents, intensities, and the observed date at which angiogenesis is observed all vary. Because of the discrepancies in the literature, it is difficult to draw conclusions about possible exposure conditions in patients. The already existing phenomena of ultrasound contrast agent induced angiogenesis needs to be validated if this therapeutic application is to transition to the clinic. For patients with vascular occlusive disease, not only do general trends need to be elucidated, but also the mechanism behind the therapy. Therefore, the first objective of this study is to develop an understanding of the angiogenic progression in UCA-treated normal muscle via a survival study. In doing so, the underlying principles of exposure conditions will be used to assess the response at 3, 6, 13, 20, and 27 days. This information will be used for the second objective: to understand how the pulse duration, PRPA, and presence or absence of contrast agents affects the response (at the peak time point for angiogenesis). Finally, the mechanism by which ultrasound and ultrasound contrast agents exert their effect will be explored using the angiogenic marker VEGF, quantitative real time PCR for VEGF mRNA expression, and capillary density as quantifiable end points.
