Abstract
Intracellular Paired-Agent Imaging (iPAI) quantifies intracellular drug targets using fluorescently-labeled small molecule imaging agents. iPAI has the potential to predict therapeutic response for individual patients but requires a patient derived xenograft (PDX) model that accurately mimics in vivo tumor heterogeneity yet is easily accessible for intravenous drug administration and rapid image collection. The chicken embryo chorioallantoic membrane (CAM) provides an intermediate, cost-effective model that provides vascularized, in vivo tumors in a matter of days (typically ~72 h) from implantation. Here, we investigate the implantation of thin (< 1 mm) cross-sectional slices (1-2 cm) of freshly excised tumor tissues from mouse xenografts. Multispectral iPAI will be performed to quantify the distribution and heterogeneity of drug targets within the tumor cross-section.
