Rat Epithelial cells derived from Leptomeningi (Meningeal) within the Nervous system.\u003c\/p\u003e\n\u003cp\u003eMeningeal cells surrounding the brain participate actively in the normal development of the central nervous system. They play important roles in stabilizing the extracellular matrix of the pial surface, organizing the radial glial scaffold, laminating the cerebellar cortex. Selective pharmacological destruction of the meningeal cells during a critical ontogenetic period leads to specific malformation of both the cerbella cortex and dentate gyrus [1]. Grafts of meningeal cells, which are derived from meninges overlying the cerebral cortex in adult rat spinal cord lesion, promote axonal regrowth [2]. Additionally, in vitro studies showed that meningeal cells chemotactically orient the migration of immature neurons but not glial cells [3]. iXCells Biotechnologies provides high quality Rat Meningeal Cells (RMC), which are isolated from rat leptomeningi and cryopreserved at P1, with \u0026gt;0.5 million cells in each vial. RMC express fibronectin and are negative for GFAP, α-smooth muscle actin and Thy1. They are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast, and fungi and can further expand for 5 population doublings in Fibroblast Growth Medium (Cat# MD-0011) under the condition suggested by iXCells Biotechnologies.\u003c\/p\u003e\n\u003ch2\u003eKey elements and design rationale\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCell identity:\u003c\/strong\u003e Epithelial cells (Primary Cells, Custom Cells)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSource context:\u003c\/strong\u003e Leptomeningi; Meningeal; Nervous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDonor background:\u003c\/strong\u003e Age: Adult\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBiosafety level:\u003c\/strong\u003e BSL-1 (follow your institution’s biosafety program and local regulations)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct-specific elements (such as tissue source, donor background, and cell classification) help frame how results should be interpreted across assays and experimental conditions.\u003c\/p\u003e\n\u003ch2\u003eBiological background\u003c\/h2\u003e\n\u003cp\u003eEpithelial cells provide barrier and transport functions across tissues, coordinating innate defense, secretion, and repair responses in the face of environmental and inflammatory stressors.\u003c\/p\u003e\u003cp\u003eAcross primary and specialty cell models, experimental outcomes can be influenced by donor heterogeneity, passage history, confluence, and media composition.
