Abstract:
Vascular-disrupting agents (VDA) kill tumor cells by selectively disrupting blood circulation in tumors. In vivo analysis of this intensely studied class of anticancer agents is invaluable for preclinical assessment of pharmacodynamic end points and effective therapeutic windows. In this review, we consider the role of intravital video microscopy in measuring tumor vascular response to VDAs, the potential of which lies in the opportunity to quantitate specific variables and to obtain real-time information on how VDAs affect tumor microcirculation.
Insights
Vascular-disrupting agents (VDAs) are anticancer drugs that target tumor blood vessels. Intravital video microscopy offers real-time insights into how these agents affect tumor circulation, aiding preclinical assessments.
Area of Science:
