Single-cell transcriptome profiling of zebrafish pancreatic beta-cells segregated by CaMPARI-based calcium labeling.

ABSTRACT: Coordination of cell activity trough Ca2+ waves enables pancreatic β-cells to secrete precise quantities of insulin in response to blood sugar. However, how the coordinating Ca2+ waves are orchestrated in space and time remains unknown. By applying functional Ca2+ imaging using CaMPARI and single-molecule RNA detection, we reveal a gene-signature depicting a molecularly and metabolically distinct state of first responder β-cells. We highlight Vitamin B6 metabolism as a signature pathway associated with the first responder β-cells .
