Quantificational Cell Behavior Analysis

Measurement of the proliferative behaviors of cells in vitro is important to many biomedical applications ranging from basic biological research to advanced industrial applications, such as drug discovery, stem cell manufacturing, and tissue engineering. Critical to such measurement is the accurate counting and localization of occurrence of mitosis, or cell division, in a cell culture. For short-period, small-scale studies, it is possible to manually identify incidents of mitosis because mitotic cells in culture tend to retract, round up, and exhibit intensified surrounding halos under phase contrast illumination. However, the need for extended-time observation and the proliferation of high-throughput imaging have made automated image analysis mandatory. We works on the algorithm development for automated cell behavior analysis in the time-lapse microscopy image sequences.
