Research Abstract

A human breast cancer cell line, MCF-7 differentiates into mammalian grand-like cells upon addition of heregulin to the culture medium. In this study, we traced changes of cellular internal states by means of Raman spectrum measurement, which is a potent method to detect multi-dimensional intracellular dynamics in single cells with minimal disruption. Analysis of the Raman dynamics up to 12 days though the differentiation process has revealed pseud-circular trajectory of the major intracellular components.
