使用氟化钙 (CaF2) 载玻片上的 Caki-2 细胞的 FTIR 显微光谱图像来构建计算模型,以便区分增殖过程中连续细胞周期的生化事件。使用多变量分析和机器学习技术(例如 PCA、PLSR 和 SVM)来突出细胞周期阶段之间的化学差异,并指出需要消除由于细胞形态而导致的光谱失真。结果显示,细胞周期相关的散射曲线使得支持向量机的训练能够以相对较高的精度识别每个细胞周期阶段,在经过 RMieS-EMSC 算法后,从 FTIR 数据中删除散射曲线。
FTIR micro-spectral images of Caki-2 cells cytospun onto calcium fluoride (CaF2) slides were used to build a computational model in order to discriminate between the biochemical events of the continuous cell cycle during proliferation. Multivariate analysis and machine learning techniques such as PCA, PLSR and SVMs were used to highlight the chemical differences among the cell cycle phases and also to point out the need for removing the distortion of the spectra due to the morphology of the cells. Results showed cell cycle dependant scattering profiles that enabled the training of a SVM in order to recognise, with a relative high accuracy, each cell cycle phase purely with the scattering curve removed from the FTIR data after being subject to the RMieS-EMSC algorithm.
