The production of insulin-producing β cells from human embryonic stem cells (hESCs) in vitro represents a promising strategy for a cell-based therapy for type 1 diabetes mellitus. To explore the cellular heterogeneity and temporal progression of endocrine progenitors and their progeny, we performed single-cell qPCR on more than 500 cells across several stages of in vitro differentiation of hESC...
Single-cell resolution lineage information is a critical key to understanding how the states of gene regulatory networks respond to cell interactions and thereby establish distinct cell fates. Here, we identify a single pair of neural stem cells (neuroblasts) as progenitors of the brain insulin-producing neurosecretory cells of Drosophila, which are homologous to islet beta cells. Likewise, we ...
The gastrointestinal hormone peptide YY is a potent inhibitor of food intake and is expressed early during differentiation of intestinal and pancreatic endocrine cells. In order to better understand the role of peptide YY in energy homeostasis and development, we created mice with a targeted deletion of the peptide YY gene. All intestinal and pancreatic endocrine cells developed normally in the...
The homeodomain transcription factor encoded by the pancreatic and duodenal homeobox gene-1 (Ipf-1) is essential for pancreatic ontogenesis. Whether Ipf-1 is also involved in the neogenesis of beta-cells in the adult pancreas is unknown. We examined whether Ipf-1 is expressed in adult human pancreatic ducts, which are thought to generate new beta-cells. In tissue sections, virtually all duct ce...
