脊椎动物的消化道发育呈现出自前向后这一共同的局部分化特点。目前已有的研究结果表明 ,控制中轴器官发育的Homeobox基因维持这种模式的作用是通过它们的表达部位体现出来的。该基因家族的异常表达可能与先天性消化道畸形的发生有着密切的关系。一、Homeobox基因的特点Homeobo
Vertebrate digestive tract development from the front to the back of this common local differentiation characteristics. The current research shows that the functions of Homeobox genes that control the development of axial axons are reflected through their expression sites. Abnormal expression of this gene family may be closely related to the occurrence of congenital gastrointestinal malformations. A, Homeobox gene features Homeobo
