【摘要】 对生物模式形成机制的探讨一直是生命科学特别是发育生物学的重要课题。我们曾应用元胞自动机方法建立了一个从单细胞及其行为到细胞与细胞、细胞与胞外环境相互作用下生物模式的形成模型。本文应用此模型,同时考虑到营养物和代谢对细胞繁殖的影响,模拟菌落的生长模式。更多还原

【Abstract】 The investigation of the mechanism of biological pattern has been an important topic of life sciences, especially of developmental biology, for a long time. We have established a cellular automata model of biological pattern formation, which defines how to form a biological pattern from individual cells and their behaviors, cell-cell interactions, and cell-environment interactions. In this paper, we use that model to simulate the growth pattern of the bacterial colonies in consideration of the effects of both nutrient and metabolite on the cell’s reproduction.更多还原
