Conditioned medium from human adipose-derived mesenchymal stem cells attenuates cardiac injury induced by Movento in male rats: role of oxidative stress and inflammation

Movento an insecticide containing spirotetramat, has been shown to cause severe toxicity in humans and rats. Due to the widespread use of the Movento in agriculture, and since the cardiac effects of this toxin have not been investigated in any study so far, in this study, for the first time, the effect of movento on the structure and function of the heart in rats was investigated. 24 adults' male Wistar rats randomly divided to 4 experimental groups: 1- control (CTL), 2- Movento (M) 3- M + Basal media (BM) 4- M + Conditioned medium (CM). Animals were subjected to deep anesthesia to record the ECG and blood pressure. H&E staining was performed to determine the degree of damage. Oxidative stress markers and inflammatory factors were investigated with related kits. In rats that received Movento's insecticide, mean arterial pressure (MAP), amplitude of the P wave and total antioxidant capacity (TAC) decreased compared to the control group and treatment with CM increased them significantly compared to M and M + BM group. Also, Movento increased histological score, MDA, TNF-α and IL-6 compared to the control group and CM significantly decreased them compared to M and M + BM groups. CM derived from mesenchymal stem cells (MSC) can be used as a therapy for heart disorders caused by movento toxin in the heart of rats. Also, it seems that this treatment could be a promising way to improve heart complications in farmers exposed to this toxin in the future.
