We are currently focusing on pancreatic beta-cell regeneration. Increasing the number of insulin-producing beta-cells might prove a better treatment for diabetes, which is at present controlled but not cured by insulin injections. Diabetes is characterized by elevated blood glucose levels, a consequence of insufficient insulin supply and/or insulin resistance. Despite mechanistic differences, both type 1 and late-stage type 2 diabetes feature depletion of beta-cells. Experimental ablation of beta-cells by chemical treatment or partial pancreatectomy in zebrafish and rodents is followed by significant recovery of the beta-cell mass, indicating that the pancreas has the capacity to regenerate. This regenerative capacity could potentially be exploited therapeutically - if the underlying mechanisms were better understood.
