Review on In-vitro Techniques and In-vivo Animals Models for Screening Diabetes and Diabetic Complications

Diabetes mellitus is a type of metabolic disorders. Various pharmaceutical interventions and animal models have been used to investigate the genetic, environmental, and etiological aspects of diabetes and its effects. In recent years for the development of ant-diabetic remedies, numerous novel genetically modified animals, pharmaceutical substances, medical techniques, viruses, and hormones have been developed to screen diabetic complications. A unique disease-treating drug with new properties is still being sought after. The current review tried to include all published models and cutting-edge techniques. Experimental induction of diabetes mellitus in animal models and in vitro methods are essential for advancing our knowledge, a thorough grasp of pathophysiology, and the creation of novel therapeutics. Animal models and in vitro techniques are necessary to develop innovative diabetic medications. New approaches and additional animal models are required for diabetes research to advance. This is particularly true for models produced via dietary modifications, which have various macronutrient compositions. In this article, we review the rodent models of diet-induced diabetic peripheral neuropathy, diabetic retinopathy, and diabetic nephropathy and critically compare the key characteristics of these micro-vascular complications in humans and the diagnostic criteria with the parameters used in preclinical research using rodent models, taking into consideration the potential need for factors that can accelerate or aggravate these conditions.
