Single-cell RNA sequencing identifies endothelial-derived HBEGF as promoting pancreatic beta cell proliferation in mice via the EGFR-Kmt5a-H4K20me pathway.

ABSTRACT:

Aims/hypothesis

Pancreatic beta cell mass is dynamically regulated in response to increased physiological and pathological demands. Understanding the mechanisms that control physiological beta cell proliferation could provide valuable insights into novel therapeutic approaches to diabetes. Here, we aimed to analyse the intracellular and extracellular signalling pathways involved in regulating the physiological proliferation of beta cells using single-cell RNA-seq (scRNA-seq) and in vitro functional assays.

Methods

Islets isolated from nulliparous mice, mice at different time points of gestation and mice at day 4 after delivery were analysed using scRNA-seq. Bioinformatics analyses of scRNA-seq data were performed to determine the heterogeneous transcriptomic characteristics
