Mouse

The laboratory mouse (Mus musculus) remains the most widely deployed mammalian model system in biomedical research. Because mice share a high degree of genomic homology with humans and can be readily subjected to precise genetic manipulations (such as knockouts, conditional Cre-Lox lines, and transgenic reporter insertions), primary murine cells are indispensable for mapping fundamental cell biology, validating intracellular signaling cascades, and conducting early-stage drug discovery.

To explore these specialized physiological niches in vitro, contemporary neuroscience and hepatology workflows rely on a targeted grid of primary mouse cells. The neuro-axial compartment is highly compartmentalized, utilizing Mouse Neural Stem Cells (MNSC) alongside distinct post-mitotic lineages including Mouse Cortical Neurons (MCoN), Mouse Striatal Neurons (MStN), and specialized immune caretakers like Mouse Microglia (MMcg). In parallel, hepatic injury and metabolic fibrosis pathways are modeled using Mouse Hepatic Stellate Cells (MHSC).

By strategically selecting from this primary cell matrix, investigators can reduce many of the signaling artifacts and altered differentiation baselines typical of immortalized lines while mapping neuro-vulnerability, tracking synaptic plasticity, and characterising localized fibroblastic transitions. However, species-specific differences in ion-channel and receptor isoforms, cellular and systemic metabolism, and immune/inflammatory regulation (including differences in NOS2/iNOS induction) create translational limitations that must be accounted for when extrapolating murine results to humans.
