Rat primary cells are freshly isolated or minimally passaged cells obtained directly from Rattus norvegicus tissues and organs. Unlike immortalized cell lines, they retain many of the morphological, transcriptomic, metabolic, and functional characteristics of their tissue of origin, making them valuable experimental models for investigating normal physiology, disease mechanisms, and responses to pharmacological interventions. Rats have long been established as important experimental models in neuroscience, cardiovascular physiology, pharmacology, toxicology, metabolism, and regenerative medicine because of their well-characterized physiology and translational relevance to human biology and disease. Although primary cells exhibit finite proliferative capacity and donor-dependent variability, they provide more physiologically relevant in vitro models than transformed cell lines for many experimental applications.
