Abstract

The bioscience research community faces for the first time the prospect of identifying and understanding the functions and interactions of macromolecules in human cells with high throughput, large scale approaches owing to the rapid advances of optical fluorescence microscopy in the past decades.  Automated digital microscopy, coupled with a large arsenal of fluorescent and other labeling techniques, offers tremendous values to localize, identify and characterize cells and molecules.  It has become a quantitative technique for probing cellular structure and dynamics and is increasingly used for cell-based assays and screens.  The new development, in turn, generates many bioinformatics challenges in developing innovative algorithms and tools to extract, classify, model, correlate, and mine image features and content from massive amounts of images for both hypothesis-driven analysis and hypothesis-generated tasks.

High content cellular imaging concerns the automation and quantitation of cellular information in a scale that is not achievable by the conventional manual microscopic approach. The technology couples automated multi-dimensional microscopy imaging and image analysis with biostatistical and data mining techniques to provide a system biologic approach in studying the cells, the basic unit of life, and potentially leads to many exciting applications in life and health sciences. In this talk, I will introduce the concept of high content cellular analysis and briefly describe selected applications in drug discovery and genomic-wide screens.
