肿瘤细胞与其环境之间的相互作用导致形成包含不同亚群的细胞以及氧气、葡萄糖和其他代谢物的陡峭梯度的微区。为了解决肿瘤微区在单细胞水平上的形成问题,本文提出了一个新的二维含时数学模型,该模型明确考虑了肿瘤细胞个体调控的生物力学过程以及氧耗对其代谢的影响。给出了肿瘤微区自组织形成的数值模拟,并讨论了这一过程的动力学。
Interactions between tumor cells and their environment lead to the formation of microregions containing nonhomogeneous subpopulations of cells and steep gradients in oxygen, glucose, and other metabolites. To address the formation of tumor microregions on the level of single cells, I propose a new two-dimensional time-dependent mathematical model taking explicitly into account the individually regulated biomechanical processes of tumor cells and the effect of oxygen consumption on their metabolism. Numerical simulations of the self-organized formation of tumor microregions are presented and the dynamics of such a process is discussed.
