多细胞生物体的发展依赖于一小套构建技术--组装、雕刻和折叠--这些技术在空间和时间上以组合的方式进行调节,以产生体内组织的多样性。这些基本过程在基因和机制的水平上在组织类型和物种之间都很保守。在这里,我们回顾的信号,图案,和生物力学的转换,发生在两个良好的研究模型系统的上皮折叠,以说明组织发育的复杂性和模块化。特别是,我们讨论了空间代码指定形态发生的可能性。为了破译这一密码,工程师和科学家需要建立定量实验系统,并开发出从基因序列到组织生物力学的多层次机制模型。反过来,胚胎发生的定量模型可以激发创造合成器官和治疗退行性组织疾病的新方法。
The development of multicellular organisms relies on a small set of construction techniques—assembly, sculpting, and folding—that are spatially and temporally regulated in a combinatorial manner to produce the diversity of tissues within the body. These basic processes are well conserved across tissue types and species at the level of both genes and mechanisms. Here we review the signaling, patterning, and biomechanical transformations that occur in two well-studied model systems of epithelial folding to illustrate both the complexity and modularity of tissue development. In particular, we discuss the possibility of a spatial code specifying morphogenesis. To decipher this code, engineers and scientists need to establish quantitative experimental systems and to develop models that address mechanisms at multiple levels of organization, from gene sequence to tissue biomechanics. In turn, quantitative models of embryogenesis can inspire novel methods for creating synthetic organs and treating degenerative tissue diseases.
