Appropriateness of islet xenotranplantation on a comprehensive scale would thirst for rigorous safety and excellence government measures to maximize transplant success. Advance of molecular tools to watchdog porcine islet cellular responses to ischemic, osmotic, mechanical and oxidative stresses during islet cell processing and post-isolation culturing would support the cerebral doodle of cytoprotective strategies aimed at improving transplant outcomes.
In addition, gene signal signatures informative for islet endowment could serve as an adjunct to physiological testing to base the suitability of islet products for transplantation. Experiment Overall Design: Nine subject Landrace sows were sacrificed, the pancreases were dissected, and islet cells loney as formerly described.
Islet preparation purity was assessed by illumination microscopy after staining with diphenylthiocarbazone and ranged between 90-95% for the preparations used. Profiles of islet cells cultured under customary conditions were compared to islet cells cultured under stress conditions with elevated glucose (16.7 mM) or appendix of inflammatory cytokines (IL-1beta, TNF-alpha, and IFN-gamma), or both, for 48 hours.
