Mouse primary cells are freshly isolated or minimally passaged cells obtained directly from murine tissues and organs. Unlike immortalized cell lines, they retain many of the morphological, transcriptional, metabolic, and physiological characteristics of their tissue of origin, making them valuable experimental models for investigating normal cellular function and disease mechanisms. Because mice are genetically tractable and share substantial genetic, molecular, and physiological conservation with humans, mouse primary cells are widely used in molecular biology, immunology, neuroscience, cardiovascular research, developmental biology, regenerative medicine, and cancer research. They are extensively employed to investigate gene function, intracellular signaling, host-pathogen interactions, pharmacological responses, and tissue-specific physiology under controlled in vitro conditions. Although their proliferative lifespan is limited and culture requirements are often cell type-specific, mouse primary cells generally provide greater physiological relevance than transformed or immortalized cell lines.
