pancreatic islet study 3 (expanded; Whittier; HGF) / normal pancreatic islet sample

Relative Expression (log2-ratio):-1.6425667
Number of Samples:3 / 7
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).
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.
