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

Relative Expression (log2-ratio):3.1689787
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.

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.

Experimental pancreatic islet study 3 (expanded; Whittier; HGF)
Human pancreatic islets cells were expanded according to Whittier protocol and treated with hepatocyte growth factor (HGF, 25 ng/ml) for 4 weeks. Expansion phase: 1000 islets of 50–150µm in diameter were purified by hand-picking after dithizone staining, partially dissociated using Versene to separate “outer” and “inner” populations, the outer population was removed. Cell clusters from the inner population were plated on HTB-9 matrix-coated dishes in RPMI-1640 supplemented with 2 mM L-glutamine, 10% FBS, and 25 ng/ml HGF. After confluence, cells were harvested using Versene containing 0.025% trypsin and subcultured (1:2).

Nasal biopsies for isolation of primary cells were taken from the lower edge of the inferior turbinate, and 2 cm from the anterior end.

Primary nasal epithelial cells from healthy subjects with no allergies were exposed to house dust mite (HDM) extract (2µg/ml) for 24 hours. Subjects (21-32 years old) were selected based on skin prick test for HDM and other common allergens. Nasal biopsies for isolation of primary cells were taken from the lower edge of the inferior turbinate, and 2 cm from the anterior end.
