Immortalized Microglia Modeling Service
Microglia are the resident immune cells of the central nervous system (CNS) and play a crucial role in maintaining homeostasis, responding to injury, and modulating neuroinflammatory responses. Compared to primary microglia, immortalized microglia cell lines offer obvious advantages, such as easier maintenance and abundant availability due to their unrestricted proliferative capacity.
Creative Biolabs is dedicated to providing high-quality immortalized microglia models to study inflammatory response, cellular dysfunction, CNS development and homeostasis.
Mouse Microglia Cell Line BV2
The BV2 cell line was derived from murine brain tissue. Notably, BV2 cells retain many functional characteristics of primary microglia, making them a choice for studying inflammation and neuroprotection mechanisms. BV2 cell line is widely used to examine cytokine production, phagocytosis, and signaling pathways, enabling the exploration of various CNS diseases, including Alzheimer's and Parkinson's disease.

Mouse Microglia Cell Line N9
The N9 microglial cell line is another pivotal model, derived from the C57BL/6 mouse. Similar to BV2 cells, N9 cells exhibit the capability to produce and secrete pro-inflammatory cytokines after LPS stimulation, as well as the ability to phagocytose apoptotic cells and Aβ fibrils.

Human Microglia Cell Line HMC3
The Human Microglial Clone 3 (HMC3) cell line was immortalized from microglia cultures, and isolated from the brain of a patient. It provides a vital platform for examining human-specific microglial functions and responses. Compared with other clones, the HMC3 cells secreted higher levels of interleukin-6 (IL-6). With this cell line, researchers can better understand the inflammatory response and migration to develop anti-inflammatory agents.

Rat Microglia Cell Line HAPI
The highly aggressive proliferating immortalized (HAPI) cell line is derived from rat neonatal microglia. These cells exhibit key microglial characteristics, including phagocytosis and the production of pro-inflammatory cytokines. They are valuable for investigating neuroinflammation, neurodegenerative diseases, and immune signaling in the central nervous system, aiding in the development of therapeutic strategies.
