Effects of steroids on the morphology and proliferation of canine and equine mesenchymal stem cells of adipose origin – in vitro research.

This investigation studied the synergistic effects of steroid therapy and stem cell transplantation, specifically highlighting how two different steroids (betamethasone and methylprednisolone) affect the growth, vitality, and structure of stem cells derived from adipose tissue in dogs and horses. The findings suggest low dosages of these steroids may enhance stem cell therapy’s effectiveness in treating degenerative joint diseases in pets without damaging the cells, which has potential applications in future veterinary medicine.

Introduction to The Study

• The study began with a discussion on the common usage of steroid injections in treating locomotive system disorders in animals. While effective in providing short-term relief, these treatments are known to cause several side effects.
• The potential use of adult mesenchymal stem cells (MSCs) as a method of treatment for these disorders was also emphasized, specifically those stem cells derived from adipose (fat) tissue (AdMSCs).
• The researchers sought to investigate the potential advantages of a combined treatment utilizing both steroids and stem cell transplantation.

Methodology

• The study evaluated the impact of two steroids, betamethasone and methylprednisolone, on the morphology (structure) and proliferation (growth) rate of AdMSCs.
• The steroids were administered at concentrations of 0.01 mg/ml, 0.1 mg/ml, and 1 mg/ml, to understand how different dosages affect the cells.

Findings

• The researchers found that the steroids generally exhibited a positive influence on the cells’ viability and growth state. This positive influence was observed when administered at concentrations of 0.01 mg/ml and 0.1 mg/ml.
• Conversely, a concentration of 1 mg/ml proved to be cytotoxic (harmful to cells).
• The researchers also noticed that the lower dosages used in the experiment (0.01 mg/ml and 0.1 mg/ml) did not alter the structure of the cells and instead helped to significantly increase cell activity.

Conclusion

• The research concluded that steroids could have a stimulating effect on the stem cells’ morphology, growth rate, and cytophysiological activity, primarily when used in lower dosages.
• The results of this study may influence future veterinary medical practices, particularly with respect to how stem cells and steroids are used in regenerative treatments for degenerative joint diseases in both dogs and horses.
