Monosodium Iodoacetate (MIA)-Induced Osteoarthritis (OA) Model

Creative Bioarray provides a monosodium iodoacetate (MIA)-induced osteoarthritis (OA) model for our clients to study the disease mechanisms or evaluate the efficacy of drug candidates. With our services, you can obtain reliable and accurate results, providing valuable insights into drug development.

OA is the most common form of arthritis among middle-aged and elderly individuals. Its etiology is complex and involves multiple factors, with the underlying pathogenic mechanisms remaining elusive. While the progression of the disease is typically slow, it can result in significant pain and disability, negatively impacting the quality of life. Given the challenges in studying OA in humans, animal models have become crucial in assessing the development of the disease and evaluating innovative treatment strategies.

Currently, the most utilized type of chemical induction is MIA, which has an inhibitory activity of glyceraldehyde-3-phosphate dehydrogenase glycolysis and induces the death of chondrocytes. In both rodents and non-rodents, the intra-articular injection causes chondrocyte destruction. When administered in rats, it causes cartilage lesions with loss of proteoglycan matrix and functional alterations with stiffness that are analogous to those seen in human osteoarthritis.

Our Monosodium Iodoacetate (MIA)-Induced Osteoarthritis (OA) Model

• Available Animal
  Rat
• Modeling Method
  After anesthetization, rats are given a single intra-articular injection of MIA through the infrapatellar ligament of the right knee.
• Endpoints
  • Behavioral test
  • Histology analysis (knee joint): H&E staining, Safranin-O/Fast Green staining
  • Mankin score
  • Serum analysis: cytokine, SOD, MDA, etc.
  • Body weight
  • Other customized endpoints
