Abstract
|
|
|
|
Organ transplantation is limited by the shortage of human organs. Many studies have sought to overcome this hurdle by using animal organs. Porcine organs, especially from miniature pigs, have been used for organ xenotransplantation rather than nonhuman primates. While the molecular profiling for transplantation is well known in humans and rodents, the situation for pigs is almost completely unknown. The present study examined protein regulation of the developing stages of the pancreatic proteome (4 day-old miniature neonate, 19 day-old miniature piglet, and 14 month-old miniature adult pigs) using two-dimensional gel electrophoresis and matrix assisted laser desorption/ionization-time of flight mass spectrometry. Thirteen different expressed spots were observed and nine were identified. The data presented within this study provides critical direction relating to the development of pancreas of miniature pigs, which will assist future proteome analysis of the pancreas, and advance our understanding of the hurdles facing xenotransplantation.
