Project description:The beta cell mass of the adult pancreas is thought to be maintained through low-level proliferation. Ductal cells have been proposed as an alternative source of beta cells in vivo, but this remains controversial. By performing detailed lineage tracing analysis, 3D imaging and single cell RNA sequencing we investigated if ductal cells contribute to the beta cell mouse in the adult mouse.
Project description:Two strains of rodent C57Bl/6J and KK/HIJ were compared to find the most suitable rodent model of obesity and type 2 diabetes. KK/HIJ become larger and glucose intolerant on standard chow but are not as well characterized as the C67Bl/6J model which has a more defined behavioral phenotype. The present study is to asses and determie the most suitable mouse model for our research. We used microarray analysis to examine changes in adult rodent pancreatic gene expression.
Project description:We report the global gene expression of mouse pancreatic cells in a pancreas-specific conditional knock-out mouse for Gata6, as compared with age-matched controls. Total RNA was extracted from the pancreas of 6-8 -week old mice of the two genotypes and analyzed. at this age, Gata6P-/- pancreata are histologically normal, but the acinar differentiation programme is already altered. we observe that loss of Gata6 causes the de-repression of ectopic non-pancreatic genes, as well as some genes involved in the mesenchymal programme.
