In developmental biology, pattern formation refers to the generation of complex organizations of cell fates in space and time. Pattern formation is controlled by genes. The role of genes in pattern formation is an aspect of morphogenesis, the creation of diverse anatomies from similar genes, now being explored in the science of evolutionary developmental biology or evo-devo. The mechanisms involved are well seen in the anterior-posterior patterning of embryos from the model organism Drosophila melanogaster (a fruit fly), one of the first organisms to have its morphogenesis studied and in the eyespots of butterflies, whose development is a variant of the standard (fruit fly) mechanism.

在 发育生物学developmental biology,中，斑图生成指的是细胞的复杂组织在时间和空间上的命运般的产生。斑图生成是由基因控制的。形态发生是由相似的基因创造出不同的解剖结构，基因在斑图生成中的作用仅是是其中的一个方面，目前演化发育生物学仍在研究这个问题。模式生物黑腹果蝇的胚胎前后图案和蝴蝶的眼点清楚地体现了这一机制，而后者的发育是果蝇的标准机制的一种变体。

In developmental biology, pattern formation describes the mechanism by which initially equivalent cells in a developing tissue in an embryo assume complex forms and functions.[3] Embryogenesis, such as of the fruit fly Drosophila, involves coordinated control of cell fates.[4][5][6] Pattern formation is genetically controlled, and often involves each cell in a field sensing and responding to its position along a morphogen gradient, followed by short distance cell-to-cell communication through cell signaling pathways to refine the initial pattern. In this context, a field of cells is the group of cells whose fates are affected by responding to the same set positional information cues. This conceptual model was first described as the French flag model in the 1960s.[7][8] More generally, the morphology of organisms is patterned by the mechanisms of evolutionary developmental biology, such as changing the timing and positioning of specific developmental events in the embryo.[9]

在发育生物学中，斑图生成描述了胚胎发育组织中最初的等效细胞呈现出复杂形态和功能的机制。 胚胎发生Embryogenesis，例如果蝇的胚胎发生，涉及到细胞命运的协调控制。模式的形成是遗传控制的，通常涉及一个场中的每个细胞沿着形态原梯度感知和响应其位置，然后通过细胞信号通路进行短距离的细胞间通信，以完善初始模式。在此背景下，细胞场 a field of cells是指通过响应同一组位置信息线索而影响其命运的一组细胞。这个概念模型最早在20世纪60年代被描述为法旗模型。更一般地说，生物体的形态是由进化发育生物学的机制所决定的，如改变胚胎中特定发育事件的时间和位置。
Possible mechanisms of pattern formation in biological systems include the classical reaction–diffusion model proposed by Alan Turing[10] and the more recently found elastic instability mechanism which is thought to be responsible for the fold patterns on the cerebral cortex of higher animals, among other things.[11][12]

菌落生长
Bacterial colonies show a large variety of patterns formed during colony growth. The resulting shapes depend on the growth conditions. In particular, stresses (hardness of the culture medium, lack of nutrients, etc.) enhance the complexity of the resulting patterns.[13] Other organisms such as slime moulds display remarkable patterns caused by the dynamics of chemical signaling.[14]

植被模式
Tiger bush is a vegetation pattern that forms in arid conditions.
[虎灌木是在干旱条件下形成的植被模式。]
Vegetation patterns such as tiger bush[15] and fir waves[16] form for different reasons. Tiger bush consists of stripes of bushes on arid slopes in countries such as Niger where plant growth is limited by rainfall. Each roughly horizontal stripe of vegetation absorbs rainwater from the bare zone immediately above it.[15] In contrast, fir waves occur in forests on mountain slopes after wind disturbance, during regeneration. When trees fall, the trees that they had sheltered become exposed and are in turn more likely to be damaged, so gaps tend to expand downwind. Meanwhile, on the windward side, young trees grow, protected by the wind shadow of the remaining tall trees[16]. In flat terrains additional pattern morphologies appear besides stripes - hexagonal gap patterns and hexagonal spot patterns. Pattern formation in this case is driven by positive feedback loops between local vegetation growth and water transport towards the growth location[17][18].

模板:FurtherPattern formation has been well studied in chemistry and chemical engineering, including both temperature and concentration patterns.[19] The Brusselator model developed by Ilya Prigogine and collaborators is one such example that exhibits Turing instability.[20] Pattern formation in chemical systems often involve oscillatory chemical kinetics or autocatalytic reactions[21] such as Belousov–Zhabotinsky reaction or Briggs–Rauscher reaction. In industrial applications such as chemical reactors, pattern formation can lead to temperature hot spots which can reduce the yield or create hazardous safety problems such as a thermal runaway.[22][19] The emergence of pattern formation can be studied by mathematical modeling and simulation of the underlying reaction-diffusion system.[19][21]

A similar effect to the 'KPT reaction' can be achieved with convolution functions in digital image processing, with a little patience, by repeatedly sharpening and blurring an image in a graphics editor. If other filters are used, such as emboss or edge detection, different types of effects can be achieved.

Calculations using models like reaction–diffusion or MClone are based on the actual mathematical equations designed by the scientists to model the studied phenomena.
