自然辩证法与胚胎诱导

辩证法与胚胎诱导

摘要

胎发育的一个特点是时空连续的细胞间相互作用,以提升细胞分化的轨迹过程。尽管还原论者在解析机械发展过程的基础中取得了巨大的成功,但是上个世纪从未终止对更全面系统理论的寻找。在此过程中多种系统理论得到提出与发展来提供对生态系统更为充足的理解。尽管为大多数现代生物学所忽视,最早出现的与之相关系统的理论的确是黑格尔的辩证法。在此以辩证法检测了Hans Spemann详细阐述的胚胎诱导全过程。得出的结论是胚胎诱导以及其揭示的分子机制可以被黑格尔辩证法重新诠释。这个例子说明了尽管辩证法有其缺陷,但是它在系统生物学理论研究中具有启发式的价值。

Dialectics and embryonic induction Abstract

A hallmark of embryonic development is the temporal-spatial continuum of cell–cell interactions, which gives rise to the trajectory of progressive cell differentiations. Despite the great reductionists’ success in dissecting the mechanistic basis of developm ental processes, the call for more holistic system theories never ceased during the last century. Various system theories were proposed to provide a more adequate understanding of biological systems, including development. Although widely ignored by modern biology, the first systematic system theory was Hegel’s dialectics. Here I examine the process of embryonic induction as elaborated by Hans Spemann in the light of dialectics. I conclude that embryonic induction and its underlying molecular mechanisms can be re-interpreted in terms of Hegel’s dialectics. The example highlights that despite its shortcomings, dialectics can be of heuristic value as a theory of systems biology.
