(a) Examples of as-collected raw spectra in PC3 and PNT1a cells; (b) the stacked mean spectra of samples according to the stages of cell proliferation. The spectra shown in part (b) have been linearly offset for comparison. The numbers (1, 2, 3) enclosed in brackets identify stage 1 (48 hours), stage 2 (72 hours), and stage 3 (96 hours) spectral measurements.
