Differentiation protocols used to generate stem cell-derived islet cells yield heterogenous cell populations. We generated a human embryonic stem cell line that reports insulin- and glucagon-expressing cells in vitro and in vivo without altering their differentiation or function. We showed some insulin- and glucagon-expressing bihormonal cells are cell-autonomously fated to become α-like cells.

Article Synopsis
  • * Research shows decreased MED15 levels in pancreatic islets from individuals with type 2 diabetes, suggesting its importance in maintaining β-cell function and health.
  • * Studies indicate that Med15 interacts with transcription factors Nkx6-1 and NeuroD1 to regulate genes crucial for β-cell maturation, and this is also seen in genetically modified human stem cells that show improved maturation when MED15 levels are increased.

As more clinically-relevant genomic features of myeloid malignancies are revealed, it has become clear that targeted clinical genetic testing is inadequate for risk stratification. Here, we develop and validate a clinical transcriptome-based assay for stratification of acute myeloid leukemia (AML). Comparison of ribonucleic acid sequencing (RNA-Seq) to whole genome and exome sequencing reveals that a standalone RNA-Seq assay offers the greatest diagnostic return, enabling identification of expressed gene fusions, single nucleotide and short insertion/deletion variants, and whole-transcriptome expression information.
