通过流式细胞术测量的细胞荧光标记的进展已经允许对细胞增殖群体的定量研究。研究(Luzyanina等人,J. Math.Biol.54:57-89,2007; J. Math. Biol.,2009年,Theor。生物医学模型。4:1-26,2007)包含以荧光强度作为结构变量的数学模型,以描述由羧基荧光素琥珀酰亚胺酯(CFSE)标记的增殖细胞随时间的演变。在这里,这个模型和几个扩展/修改进行了讨论。改进的建议,提出和分析方面的统计意义模型的解决方案和实验数据之间更好的协议。这些研究表明,新的衰变/标记损失和时间依赖性有效增殖和死亡率确实提供了模型与数据的改进拟合。所观察到的变异性/噪声的数据的统计模型进行了讨论与不确定性量化的影响。由此产生的新的细胞动力学模型应该证明是有用的增殖检测跟踪和建模,在生物医学科学中的许多应用。
Advances in fluorescent labeling of cells as measured by flow cytometry have allowed for quantitative studies of proliferating populations of cells. The investigations (Luzyanina et al. in J. Math. Biol. 54:57–89, 2007; J. Math. Biol., 2009; Theor. Biol. Med. Model. 4:1–26, 2007) contain a mathematical model with fluorescence intensity as a structure variable to describe the evolution in time of proliferating cells labeled by carboxyfluorescein succinimidyl ester (CFSE). Here, this model and several extensions/modifications are discussed. Suggestions for improvements are presented and analyzed with respect to statistical significance for better agreement between model solutions and experimental data. These investigations suggest that the new decay/label loss and time dependent effective proliferation and death rates do indeed provide improved fits of the model to data. Statistical models for the observed variability/noise in the data are discussed with implications for uncertainty quantification. The resulting new cell dynamics model should prove useful in proliferation assay tracking and modeling, with numerous applications in the biomedical sciences.
