Morphogenetic plasticity of adult human pancreatic islets of Langerhans

Improvement of the functionality of pancreatic Langerhans islets via reduction of bacterial contamination and apoptosis using phenolic compounds

Objective(s): During type-1 diabetes treating by pancreatic islet transplantation, increasing oxidative stress and microbial contaminations are the main reasons of transplantation failure. In this study, we evaluated anti-apoptotic, antioxidant and antimicrobial potentials of phenolic compounds called ellagic acid (EA) and silybin on rat pancreatic islets. Materials and Methods: By doing MTT as...

In vitro development of islets from human adult pancreatic tissues

The role of Langerhans islets in pancreatic ductal adenocarcinoma.

An intimate relationship between the exocrine and endocrine pancreas has been convincingly demonstrated in recent years. Animal experiments have shed some light into the complex dialog between the two tissues. This interaction is pronounced in diseases of the pancreas, especially in experimentally-induced and human pancreatic cancers. New evidence highlights the importance of intact islets in t...

Cryopreservation of Human Pancreatic Islets

MONOPHASIC STATE OF INSULIN SECRETION IN ISOLATED RAT ISLETS OF LANGERHANS BY K+, Ca2+ AND GLUCOSE

Isolation of rat islets of Langerhans was carried out by using collagenase and the destruction of exocrine tissue was performed through the injection of Hanks' solution into the common bile duct. The identification of the islets was done by techniques including the use of a stereomicroscope against a black background. Vital staining was done by an injection of neutral red solution through t...
