论文摘要
生物学的模式可以视为预定，或者是由自组织不稳定引起的。因此，模式的变异性可以解释为不稳定的痕迹，从噪声中生长出来。因此，可变性可以暗示一种潜在的形态发生机制。在这里，我们介绍了水母aurelia的胃血管系统的可变性。在这种变异中，运河与相关的重新连接之间出现了典型的偏见重新连接。这两种现象都可以解释为机械效应的痕迹，胃口管周围组织的游泳收缩以及内部的平均流体压力。这揭示了胃网络作为研究循环网络形态发生和发挥形态发生机制的模型系统。
Patterns in biology can be considered as predetermined, or arising from a self-organizing instability. Variability in the pattern can thus be interpreted as a trace of an instability, growing out from noise. Variability can thus hint toward an underlying morphogenetic mechanism. Here we present the variability of the gastrovascular system of the Jellyfish Aurelia. In this variability emerge a typical biased reconnection between canals, and correlated reconnections. Both phenomena can be interpreted as traces of mechanistic effects, the swimming contractions on the tissue surrounding the gastrovascular canals, and the mean fluid pressure inside them, respectively. This reveals the gastrovascular network as a model system to study morphogenesis of circulation networks and the morphogenetic mechanisms at play.
