pancreatic islet study 3 (re-differentiated; PPRF; 8d) / normal pancreatic islet sample

Relative Expression (log2-ratio):-4.8534026
Number of Samples:2 / 7
Experimental pancreatic islet study 3 (re-differentiated; PPRF; 8d)
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 8 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 1.0 ug/ml.
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.

pancreatic islet study 3 (expanded; PPRF) / normal pancreatic islet sample

Relative Expression (log2-ratio):-4.5792933
Number 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.

bronchial epithelial cell differentiation study 1 (day28) / bronchial epithelial cell differentiation study 1 (subconfluent)

Relative Expression (log2-ratio):4.5647087
Number of Samples:3 / 3
Experimental bronchial epithelial cell differentiation study 1 (day28)
Differentiated normal human bronchial epithelial cell (NHBE) cultured for 28 days in an air-liquid interface (ALI) system. At this time point cells were fully differentiated and formed a polarized, pseudostratified mucociliary epithelium. In order to generate the ALI culture, undifferentiated cells were grown under submerged conditions in bronchial air-liquid interface (B-ALI) growth basal medium supplemented with expansion media. When cells reached confluency (after 3-5 days), an air-liquid interface culture (ALI system) was created by removing the apical medium and replacing the medium of the basal compartment with B-ALI differentiation medium. During the 28 days culture medium was replaced every 48 hour.
Control bronchial epithelial cell differentiation study 1 (subconfluent)
Subconfluent undifferentiated normal human bronchial epithelial cell (NHBE) cultured for 1-2 days under submerged conditions in bronchial air-liquid interface (B-ALI) growth basal medium supplemented with expansion media. At this time point cells still grew dispersed in the culture insert and covered 70% of the insert.
