Figure 2: Comparison of the division of 580 nm transmittance ratio on Papanicolaou-stained cultured cells (n=300) Non-cancer cells: NHDF, COS-7; cancer cells: LS-180, MCF-7, A549, Kato-III. The 530 nm/580 nm transmittance ratio was significantly higher (pale red) in cancer cells (109.1±6.5%) than in non-cancer cells (95.2 ± 4.2%) (p<0.001), and the 630 nm/580 nm transmittance ratio was significantly lower (dark blue/green) in cancer cells (45.7 ± 7.7%) than in non-cancer cells (64.2 ± 8.6%) (p<0.001).
