Abstract 4262: Combined 3D quantitative imaging and 3D cell culture for cancer drug discovery

Monitoring drug activity in multicellular tumor spheroid in vitro models is an important challenge as these 3D models have demonstrated their major relevance in pharmacological screening and anticancer drugs evaluation (1). Optical microscopy coupled to the selective plane illumination microscopy (SPIM)3D microscopy, and, and automatic automated images processing and quantitative analysis are promising approaches to process optimizes the evaluation of drug response in a 3D cell culture models with, in a high/mediumhigh throughput screening waycapabilities. BIOMIMESYS® used as a 3D cell model is based on hyaluronic to provide an in vivo like environment to the cells. The In this study the effects of the topoisomerase I inhibitor Topotecan were investigated on colon adenocarcinoma HCT-116 3D cell culture. Spheroids were prepared and grown in BIOMIMESYS® used as a 3D cell model isa matrix based on hyaluronic acid tothat provides an in vivo like environment to the cells. was monitored and coupled with mMorphometric parameters and with nuclei fluorescence markers were used to monitor analysis for drug activity. Data provideand to characterization characterize of both cytostatic and cytotoxic effects of this drug withon the basis of both quantitative 3D and imaging of the mechanisms. These data highlight the relevance of combining a biomimetic microenvironment for 3D cell culture recreating the the in vivo features of a tumor cell population biology, together with and high resolution content microscopy-based quantification for drug screening. This biomimetic model provides an innovative platform for the in-depth analysis of tumor development and for the discovery or the characterization of novel therapeutic targets.
