Outline of Final Research Achievements |
We have developed a prototype of in silico cancer multicellular spheroid assay. The goal is evaluation and prediction of antiproliferative activity in cancer spheroid forming process. A forming process is simulated based on time-laps images of the in vitro spheroid assay process. The consistency of these process is preserved by matching both growth curves. As for a cellular particle, the number of generation from the first in the spheroid forming process is assigned as its attribute. The necrotic region is generally specified by stained sections of spheroids. Volume ratio of the obtained necrotic region to the spheroid was roughly estimated. When necrotic generation would be assumed in silico, the volume ratio of the necrotic generation to the whole was estimated. These ratios were approximately equal. They imply there did not exist contradiction in these ratios and demonstrate the in silico assays have the possibility of evaluation and prediction of antiproliferative activity.
