Background: Cardio-dysfunction is one of the complications in patients with diabetes mellitus (DM). This paper aimed to investigate if oral administration of green tea Epigallocatechin-3-gallate (EGCG, E) and transplantation of adipose-derived stem cells (ADSC) show cross effects on the treatment of cardiomyopathy in rats with type 1 DM.
Materials and methods: Wistar male rats were divided into four groups (each group contained 8 animals) including sham, DM (diabetic group), DM + ADSC (DM group with ADSC treatment) and DM + ADSC + E (DM + ADSC group with oral administration of EGCG).
Results: Pathological parameters including hypertrophy, inflammation, and fibrosis were activated in DM group. By contrast, all parameters were significantly improved in treatment group (DM + ADSC group). In addition, improvement of pathological parameters in DM + ADSC + E was significantly better than DM + ADSC.
Conclusion: We found that EGCG can increase expression of survival marker in ADSC under high glucose environment and reduce serum oxidative stress in DM rats.
