Outline of Final Research Achievements

We observed WBCs and five cell line cells flowing in the chamber by quantitative phase microscopy (QPM) that provides quantitative morphological information with high contrast without staining. Then, we extracted certain features from the obtained images as training data for pattern recognition, and created an algorithm to differentiate WBCs from cell lines. The obtained algorithm successfully differentiated WBCs from cell lines (AUC=0.99). Our label-free, non-cytotoxic cell recognition method based on the features of QPM images has the potential to serve as a novel method for cell recognition and negative selection of circulating tumor cells (CTCs).
