Summary
# Editorial Summary: Cytokine Stability in Stored Equine Autologous Conditioned Serum Autologous conditioned serum (ACS) has become a cornerstone of regenerative medicine in equine practice, with its therapeutic benefits largely attributed to anti-inflammatory cytokines and chemokines; however, practitioners have lacked evidence regarding how storage conditions affect these critical bioactive molecules. Researchers analysed cytokine and chemokine concentrations in ACS samples stored under both controlled laboratory conditions and practical veterinary storage scenarios, using standardised immunoassay methods to quantify key mediators across different timepoints. Their findings demonstrated that concentrations of selected cytokines and chemokines remained stable and comparable between the defined and practically relevant storage conditions tested, providing reassurance that standard clinical storage protocols do not substantially degrade the therapeutic components of ACS. These results are particularly valuable for field practitioners who cannot maintain ideal laboratory conditions, suggesting that ACS prepared and stored under typical yard or clinic circumstances maintains its biological activity. Further work characterising which specific storage variables (temperature fluctuations, light exposure, container type) most influence bioactive molecule stability would help optimise protocols and ensure consistency in treatment efficacy across different practice settings.

Practical Takeaways
- •You can store ACS under practical conditions without worrying about significant loss of anti-inflammatory cytokines and chemokines that mediate its therapeutic effects
- •Storage flexibility may improve clinic workflow and allow flexibility in scheduling ACS treatment applications
- •Verify your specific storage protocol matches the conditions tested in this study to ensure maintained efficacy
Key Findings
- •Cytokine and chemokine concentrations in autologous conditioned serum remain stable across defined and practically relevant storage conditions
- •Storage conditions do not significantly compromise the bioactive molecule profile of ACS used in equine practice
- •ACS maintains therapeutic potential of anti-inflammatory and regenerative biomolecules after storage
