Experimental HCC study 20 (CDX; Hep-G2; ectopic)
Tumor tissue biopsy samples from Hep-G2 cell line-derived xenograft (CDX) ectopically generated in SCID mice by injecting hepatocellular carcinoma cells subcutaneously.

Experimental diabetes type 2 study 27 (LCM)
Pancreatic islet samples obtained from type 2 diabetic (T2D) phenotyped pancreatectomized patients (PPP) and isolated by laser capture microdissection (LCM). Islets specimens were retrieved by LCM from snap-frozen surgical specimen from patients who underwent pancreatectomy for pancreatic diseases. Histopathology of the resected tissue did not reveal insulitis in any PPP. Patients age <18 years were excluded. Patients with type 2 diabetes had fasting glycemia ≥7.0 mmol/l; HbA1C ≥6.5% and history of diabetes for >1 year.
Control diabetes type 2 study 27 (enzymatic)
Pancreatic islet samples obtained from type 2 diabetic (T2D) patients and isolated by enzymatic digestion. Well-preserved islets were isolated by collagenase digestion of pancreas from brain-dead organ donors which suffered from type 2 diabetes. After 2±1 days of culture, islets were successfully hand-picked and processed for further analyses. Type 2 diabetes was diagnosed based on clinical history, treatment with glucose-lowering drugs, and lack of anti-GAD65 autoantibodies.
