Primary cells isolated from veterinary and agricultural species provide physiologically relevant in vitro models for basic, veterinary, agricultural, and translational research. Freshly isolated or minimally passaged primary cells retain many of the morphological, transcriptomic, metabolic, and tissue-specific functional characteristics of their tissue of origin, making them more representative of native biology than immortalized cell lines. The choice of species depends on the biological question, as each model offers distinct anatomical, physiological, immunological, developmental, or metabolic characteristics that support diverse areas of biomedical, veterinary, and comparative research.
