Summary
# Editorial Summary When generating equine monocyte-derived dendritic cells (eqMoDC) in vitro for immunological research or therapeutic applications, the choice of serum supplement has significant practical consequences. Ziegler and colleagues compared dendritic cells cultured with horse serum against the laboratory standard of fetal bovine serum (FBS), examining gene expression patterns, morphological development, viability, and functional immune capacity. Although microarray analysis revealed comparable gene expression profiles between the two groups, cultures supplemented with horse serum demonstrated superior cell viability during differentiation, more characteristic dendritic cell morphology, and critically—markedly enhanced ability to prime T lymphocytes whilst generating substantially less non-specific proliferation. These findings suggest that horse serum represents a biologically more relevant supplement for eqMoDC generation, potentially improving the reliability and translational validity of in vitro immunological studies and any future cell-based therapeutic protocols in equine medicine.
