Redifferentiation of Expanded Human Pancreatic β-Cell-derived Cells by Inhibition of the NOTCH Pathway

Abstract excerpt

In vitro expansion of β-cells from adult human pancreatic islets would overcome donor β-cell shortage for cell replacement therapy for diabetes. Using a β-cell-specific labeling system we have shown that β-cell expansion is accompanied by dedifferentiation resembling epithelial-mesenchymal transition and loss of insulin expression. Epigenetic analyses indicate that key β-cell genes maintain open chromatin...
