Raman dynamics of cell differentiation. (A) Plots of all Raman spectra in the PC1/PC2 plane. Each panel refers to the spectra obtained on the indicated day of differentiation (solid dots represent the indicated day, and open dots represent the other days for comparison). (B) Three characteristic spectra in the PC1/PC2 plane. The positions of the spectra in the PC1/PC2 plane are indicated by arrows in A. Spectra I–III are rich in proteins, lipids, and water, respectively. (C) Changes in the PC3 scores were plotted in the PC2/PC3 plane with the days of differentiation (see Fig. S3 for the plots in the PC1/PC3 plane).
