为了配合了解遗传学与临床的关系,有必要复习一下胰腺的胚胎发育。悉知胰腺是机体的一个重要器官。从解剖学、组织学、胚胎学、生理学角度,去研究胰腺的早期发育及其在发育的各环节的影响因素及基因的决定因素,将在对后天产生的一些先天性异常,从认识上会更深刻,从治疗角度可能更有针对性,使得对胰腺外分泌、胰岛β细胞的发育和胰岛素的产生等更精细的了解有重要意义~([1])。成人的胰腺大致重达60~170克,长13~25cm,胰腺的外分泌功能是分泌消化酶等进入十二指肠;胰腺的内分泌功能由Langerhans小岛完成,胰岛由四种不同类型细胞等组成,其
In order to understand the relationship between genetics and clinical, it is necessary to review the embryonic development of the pancreas. Knowing the pancreas is an important organ of the body. From anatomy, histology, embryology, physiology, to study the early development of the pancreas and its influencing factors in all aspects of development and the determinants of genes will be some of the congenital anomalies arising from the day after tomorrow, from the cognitive will More profound, from a therapeutic point of view may be more targeted, making the pancreatic exocrine, pancreatic β-cell development and insulin production more important understanding of great significance (1). The adult pancreas weighs approximately 60 to 170 grams and grows 13 to 25 cm long. The exocrine function of the pancreas is secretion of digestive enzymes and the like into the duodenum. The endocrine function of the pancreas is accomplished by the island of Langerhans, which is composed of four different types of cells ,its
