when transplanted into a mouse model of diabetes mellitus, modified human α-cells can reverse symptoms of diabetes mellitus. This study provides evidence to suggest that the adaptive

capacity of adult cells is greater than previously thought. In the present study, the team investigated whether human pancreatic cells are able to adapt in the same way mouse pancreatic

cells can. They first sorted pancreatic cells from patients with diabetes mellitus and healthy donors by cell type, and focused on two of the non-insulin-producing cells, α-cells and

γ-cells. “We knew that α-cells in mice upregulate several key β-cell transcription factors, such as PDX1 and MAFA, following β-cell ablation,” adds Herrera. “Therefore, we decided to express

these transcription factors in isolated purified labelled human α-cells and γ-cells.” This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through
