五指山豬胰腺胚后發(fā)育的形態(tài)學(xué)觀察
[Abstract]:The pancreas is an important digestive gland with both exocrine and endocrine functions. Islet transplantation has become an ideal approach for the treatment of diabetes mellitus, and porcine islets are considered to be a suitable donor source. The pancreas of Wuzhishan pigs at the age of 10 days, 40 days old and 6 months old was used as the experimental material. The methods of gross anatomy, histology and immunohistochemistry were used. The postembryonic development of pancreas in Wuzhishan porcine was systematically studied from the point of view of morphology. The results showed that the pancreas of Wuzhishan pig could be divided into pancreatic body, Zuo Ye (splenic lobe), right lobe (12 intestinal lobe), connecting leaf and connecting bridge. The distribution areas of insulin immunoreactive cells in the pancreas of Wuzhishan pigs were 66.25 鹵18.191 渭 m2, 72.13 鹵14.45 渭 m2, 942.87 鹵15.59 渭 m 21467.55 鹵23.46 渭 m ~ 3313.04 鹵41.74 渭 m ~ 2, respectively. The distribution areas of glucagon immunoreactive cells were 227.91 鹵7.51 渭 m ~ 2271.94 鹵14.76 渭 m ~ 2, 3624.02 鹵28.91 渭 m ~ 2, 6531.8 鹵48.98 渭 m ~ 2, 12510.09 鹵65.25 渭 m ~ 2, and 15.69 鹵3.61 渭 m ~ 21.58 鹵2.13 渭 m ~ 2198.28 鹵16.62 渭 m ~ 2384.53 鹵35.46 渭 m ~ 2873 鹵25.02 渭 m ~ 2, respectively. It can be seen that the number of pancreatic islet formation cells in Wuzhishan porcine pancreas after embryo increases with the increase of age, and each major component cell has the ability to differentiate and proliferate before 6 months of age. To sum up, the morphological characteristics of pancreas of Wuzhishan pig after embryo changed with the age of day, and the number of pancreatic islets increased with the increase of age, and the main constituent cells had the ability of differentiation and proliferation before 6 months of age. The results of this study will provide morphological data for the study of pancreas genesis and the treatment of diabetes mellitus and other pancreatic diseases in Wuzhishan pigs.
