Preclinical Safety Assessment of Deferoxamine-preconditioned Canine Adipose Tissue-derived Mesenchymal Stem Cells.

BACKGROUND/AIM: In the pursuit of translating stem cell therapy technology into clinical practice, ensuring the safety and efficacy of treatments is paramount. Despite advancements, the effectiveness of stem cell applications often falls short of clinical requirements. This study aimed to address the challenge of limited efficacy by investigating the safety and effectiveness of canine adipose tissue-derived mesenchymal stem cells (cATMSCs) preconditioned with deferoxamine (DFO).

MATERIALS AND METHODS

Different concentrations of DFO were used to evaluate its impact on cATMSC activity. The therapeutic potential of these preconditioned cells was validated using a mouse model of systemic inflammation. Comprehensive evaluations, including clinical hematological and radiological assessments before and after intravenous injection of preconditioned cells were conducted.

RESULTS

The study showed a notable reduction in inflammatory markers and an overall decrease in the inflammatory response in the mouse model. The data collected from the clinical hematological and radiological assessments provided essential insights.

CONCLUSION

This study lays the groundwork for the future clinical deployment of DFO-preconditioned cATMSCs, demonstrating their potential to improve the efficacy and safety of stem cell therapies.
