Isolation of live human δ cells for genetic and functional analysis

Investigations of human pancreatic islets have been empowered by strategies to isolate and study live islet cell subsets, like β cells and α cells. To advance experimentation with human islet δ cells, which remain relatively understudied, we generated combinatorial cell sorting approaches to separat...

description Investigations of human pancreatic islets have been empowered by strategies to isolate and study live islet cell subsets, like β cells and α cells. To advance experimentation with human islet δ cells, which remain relatively understudied, we generated combinatorial cell sorting approaches to separate human δ cells from β cells, yielding highly-enriched human δ cells. We used molecular analysis, immunohistology, and electroporation-based targeting to demonstrate the quality of δ cell purification. We also demonstrated the feasibility of prospectively studying human δ cell function in pseudoislet organoids. Innovations detailed here should promote discovery of genetic, signaling and physiological mechanisms governing δ cell function and roles in human islets.
