Cell microarrays in drug discovery

Abstract

There is an increasing need for systematic cell-based assays in a high-throughput screening (HTS) format to analyze the phenotypic consequences of perturbing mammalian cells with drugs, genes, interfering RNA. Taking advantage of the recent progress in microtechnology, new cell microarrays are being developed and applied to a large range of issues in metazoan cells. This article compares different approaches and evaluates their potential use in the drug discovery process. Although still an emerging technology, cell microarrays hold great promise to optimize the efficiency:cost ratio in cell-based HTS.
