Streptozotocin induced hyperglycemia in the axolotl
Developmental Dynamics, Volume 255, Issue 6, Page 567-584, June 2026.Abstract Background Diabetes is a group of diseases characterized by loss of β cell mass and/or function, resulting in hyperglycemia. With no established curative treatment, this has initiated research in β cell regeneration. Current animal models have either limited regenerative capacity (mice) or small size and evolutionary distance from humans ...
