Diabetes – Type 1 Diabetes Mouse Models
Test your novel investigational therapy’s effect on glycemic control and glucose tolerance thanks to InnoSer’s expertise in Type 1 diabetes mouse models
Type 1 Diabetes Mouse Models Key CharacteristicsÂ
Type 1 Diabetes mouse models are established either via chemical induction (e.g., STZ or alloxan-induced diabetes) or via genetic modifications (e.g., NOD mouse model). STZ or alloxan chemically-induced models result in targeted beta cell destruction and are flexible for finetuning the level of beta cell ablation and the degree of hypoglycemia. The genetic NOD mouse model is prone to T1D development via autoimmune islet destruction, making them of particular interest to evaluate immune-modulatory drugs. Key readouts include glucose tolerance testing, evaluation of immune cell infiltration and islet destruction, beta cell and islet evaluation, blood biomarkers, hormone quantification, and histological and clinical endpoints.Â
InnoSer’s type 1 diabetes mouse models and readouts, therefore, arise as suitable efficacy models for therapies aimed to target auto-immunity, promote beta-cell regeneration, and facilitate research of novel approaches ranging from (stem) cell therapies, small molecules to hormone modulating approaches or gene therapies.  Test your novel investigational therapy’s efficacy on glycemic control and glucose tolerance in a fast and golden standard experimental diabetes mouse model with full tailoring flexibility.Â

Type 1 Diabetes Mouse Models Sample Data
Early Signs of Diabetic Kidney Disease Following Alloxan-Induced T1D in Mice: Morphological and Biochemical Changes
Following chemical T1D diabetes induction (Alloxan), signs of development of early diabetic kidney disease such as distorted and enlarged glomeruli become apparent (B) compared to normal healthy (control) conditions (A). Quantitative analysis of the glomerulus area (in pixels) was performed in control mice and alloxan-induced diabetic mice. The diabetic group exhibited a significant increase in glomerulus area indicating glomerular hypertrophy, a characteristic feature of diabetic nephropathy(C). (D) BUN levels were significantly elevated in the diabetic group compared to healthy controls, indicating the development of diabetic kidney disease.
Islet Atrophy and Reduced Plasma C-Peptide Levels Following Alloxan-Induced T1D in Mice
Following chemical T1D diabetes induction (Alloxan), compared to control mice (A) type 1 diabetic mice show islet atrophy (B). Drop in mouse c-peptide plasma as a surrogate marker for insulin is observed in alloxan-type 1 induced mice compared to control mice.Â
Imaging of Transplanted Islets in Diabetic Mouse Model
(A) brightfield microscopy of transplanted islets under the kidney capsule in a diabetic mouse model. (B) immunofluorescent staining of the same islets, with pancreatic beta cells stained for insulin (green) and pancreatic alpha cells stained for glucagon (red). Nuclei are counterstained with DAPI (blue).
Glucose measurement for chemically induced and insulin treated diabetic mice after 14 days
Examine in vivo functionality of transplanted islet cell preparation after transplantation under the kidney capsule or subcutaneous transplantation sites. C-peptide levels are followed up to discriminate between insulin secreted by the mouse pancreas islets and transplanted cells. Diabetes reversal can be used to show therapeutic efficacy of your cell therapy product
Static Glucose Stimulated Insulin Secretion (GSIS) Assay
Static GSIS assays can be performed to examine the effects on insulin secretion after glucose stimulation. The assay can be performed with cell lines (INS1E, MIN6) or primary cell preparations.
