pancreatic islet study 3 (expanded; PPRF) / normal pancreatic islet sample
Relative Expression (log2-ratio):-9.850002Number of Samples:2 / 7
| Experimental | pancreatic islet study 3 (expanded; PPRF) |
| Human pancreatic islets were isolated from a cadaveric donor. The population was 70% pure in mature islets, which was determined by dithizone staining. Islets cells were expanded according to Pharmaceutical Production Research Facility Protocol (PPRF) for 6 weeks. Expansion phase: Approximately 2,500 islet equivalents were seeded onto 75-cm2 fibronectin-coated tissue culture-treated flasks in a proprietary serum-free medium (PPRF medium). The serum-free PPRF medium was supplemented with 30% serum-free mesenchymal-conditioned medium. When the cell migration resulted in the formation of large-size colonies, the cells were harvested by trypsinization and replated into new tissue culture flasks. Once the cells reached near confluence (80–90%) in monolayer, they were trypsinized, counted, and subcultured at a density of 5,000 cells per cm2. Thereafter, cells were serially passaged using the same protocol. | |
| Control | normal pancreatic islet sample |
| Pancreatic islets were obtained from seven donors aged between 37 and 70 years and body mass index between 22 and 27. Functional islets were cultured in CMRL 1066 supplemented with 10% FCS, 1% glutamine, 5.6 mM glucose, 1 mM HEPES, 110 U/ml penicillin, and 110 g/ml streptomycin for 7 days or immediately processed after isolation. |
pancreatic islet study 3 (re-differentiated; PPRF; 4d) / normal pancreatic islet sample
Relative Expression (log2-ratio):-9.574802Number of Samples:2 / 7
| Experimental | pancreatic islet study 3 (re-differentiated; PPRF; 4d) |
| Human pancreatic islets were isolated from a cadaveric donor. The population was 70% pure in mature islets, which was determined by dithizone staining. Islets cells were expanded for 6 weeks and re-differentiated for 4 days according to Pharmaceutical Production Research Facility (PPRF) Protocol. Re-differentiation phase: For induction of expanded cells to differentiate into islet-like cell clusters, the cells were seeded into 60 mm ultra-low attachment dishes in serum-free CMRL-1066 supplemented with 4 mM L-glutamine, 1% BSA, insulin (10 g/ml), transferrin (5.5 g/ml), sodium selenite (6.7ng/ml), and 1% antibiotic antimycotic solution at a density of 6.0 x 10EXP6 cells per dish. The induction medium was further added with islet neogenesis-associated protein (INGAP) peptide at a concentration of 1.0ug/ml. | |
