在肢体中产生软骨(软骨形成的图案)是发育生物学中关于形态出现的最好的研究例子之一。理论研究的核心是努力了解在胚胎肢体中建立软骨分布特征的机制,这定义了成熟肢体中未来出现的骨骼的位置和形状。这篇综述文章概述了丰富的数学和计算模型文献的历史和现状,这些模型试图对这个问题做出贡献。我们描述了通过与各种化学场相互作用的肢体生长和成形机制的模型,以及解决胚胎间充质组织内在自组织能力的模型,如反应-扩散模型和机械力化学模型。我们讨论了这些模型对目前对脊椎动物肢体软骨形成的理解的贡献,以及它们与实验学家提出的各种概念模型的关系。出生缺陷研究(C部分)96:176-192,2012。©2012 Wiley期刊,Inc.
The production of cartilage (chondrogenic patterning) in the limb is one of the best‐studied examples of the emergence of form in developmental biology. At the core of the theoretical study is an effort to understand the mechanism that establishes the characteristic distribution of cartilage in the embryonic limb, which defines the future sites and shapes of bones that will be present in the mature limb. This review article gives an overview of the history and current state of a rich literature of mathematical and computational models that seek to contribute to this problem. We describe models for the mechanisms of limb growth and shaping via interaction with various chemical fields, as well as models addressing the intrinsic self‐organization capabilities of the embryonic mesenchymal tissue, such as reaction‐diffusion and mechanochemical models. We discuss the contributions of these models to the current understanding of chondrogenesis in vertebrate limbs, as well as their relation to the varied conceptual models that have been proposed by experimentalists.
