α-cell role in β-cell generation and regeneration

JF Habener, V Stanojevic - Islets, 2012 - Taylor & Francis
This review considers the role of α-cells in β-cell generation and regeneration. We describe
recent evidence obtained from lineage-tracing studies showing that α-cells can serve as …

[HTML][HTML] Cdk4 regulates recruitment of quiescent β-cells and ductal epithelial progenitors to reconstitute β-cell mass

JH Lee, J Jo, AA Hardikar, V Periwal, SG Rane - PloS one, 2010 - journals.plos.org
Insulin-producing pancreatic islet β cells (β-cells) are destroyed, severely depleted or
functionally impaired in diabetes. Therefore, replacing functional β-cell mass would advance …
