人和鸡肠道的绒毛以类似的逐步进行的方式形成,其中间充质和附着的上皮首先折叠成纵向脊,然后是Z字形图案,最后是单个绒毛。我们发现,这些步骤villification取决于顺序分化的不同平滑肌层的肠道,限制扩张的增长内胚层和间充质,产生压缩应力,导致他们的屈曲和折叠。一个定量计算模型,结合测量性能的发展肠道,概括的形态学模式在各种物种的villification。这些结果提供了一个机制的理解,形成这些精心制作的肠道衬里,为营养吸收提供足够的表面积至关重要。
The villi of the human and chick gut are formed in similar step-wise progressions, wherein the mesenchyme and attached epithelium first fold into longitudinal ridges, then a zigzag pattern, and finally individual villi. We find that these steps of villification depend upon the sequential differentiation of the distinct smooth muscle layers of the gut, which restrict the expansion of the growing endoderm and mesenchyme, generating compressive stresses that lead to their buckling and folding. A quantitative computational model, incorporating measured properties of the developing gut, recapitulates the morphological patterns seen during villification in a variety of species. These results provide a mechanistic understanding of the formation of these elaborations of the lining of the gut, essential for providing sufficient surface area for nutrient absorption.
