Summary
# Editorial Summary Equine recurrent airway obstruction (RAO) shares considerable pathological similarities with human asthma, yet the underlying role of airway fibroblasts in equine disease remains poorly characterised—a significant knowledge gap given that these cells drive structural remodelling of lung tissue in comparable human conditions. Franke and colleagues isolated primary equine bronchial fibroblasts and systematically evaluated how two different serum supplements (fetal bovine serum versus horse serum) affected their growth kinetics and differentiation capacity, establishing protocols for maintaining viable cultures. Horse serum proved superior to fetal bovine serum for supporting fibroblast proliferation and maintaining phenotypic characteristics more representative of the in vivo equine airway environment. These findings provide farriers, veterinary surgeons, and physiotherapists with an evidence base for understanding fibroblast behaviour in RAO pathogenesis, potentially opening new avenues for investigating whether targeted interventions (whether mechanical, pharmacological, or nutritional) might modulate the fibrotic remodelling that characterises chronic airway disease in performance horses. The ability to culture equine bronchial fibroblasts reliably using species-matched serum represents a methodological foundation for future investigations into the cellular mechanisms underlying airway obstruction and remodelling in horses.

Practical Takeaways
- •This foundational work enables future research into fibroblast involvement in equine RAO, potentially leading to better understanding of airway remodeling mechanisms
- •Use of horse serum rather than bovine serum in equine fibroblast research ensures physiologically relevant results that better translate to clinical disease
- •Improved understanding of airway fibroblast biology may support development of targeted therapies for chronic respiratory disease in horses
Key Findings
- •Primary equine bronchial fibroblasts were successfully isolated and characterized for the first time
- •Horse serum supported superior growth and differentiation of equine bronchial fibroblasts compared to fetal bovine serum
- •Defined culture medium using species-appropriate serum is essential for accurate in vitro modeling of equine airway fibroblast behavior
