Overview
The Immortalized Mouse Astrocytes- SV40 T (IMA 2.1) is a suitable cell line for studies in astrocyte functions. This cell line is unique in that it is capable of metabolizing the parkinsonian toxin MPTP (to MPP+) and is responsive to pro-inflammatory stimuli.
Key elements and design rationale
- Model identity: Immortalized Mouse Astrocytes - SV40T (IMA2.1) is supplied as an immortalized cell line derived from Mouse brain.
- Growth properties: Adherent, stellate shaped
- Growth conditions: For optimal cell culture, we recommend using PriCoat™ T25 Flasks (G299) or coating your preferred vessels with Applied Cell Extracellular Matrix (G422). PriGrow III (TM003) + 10% FBS(Regular*) + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂. *Do not heat-inactivate
- Product format: Frozen, BSL-2
This cell-based model is generally used in neurobiology, differentiation, and cell signaling studies. Donor/background information is available for contextual interpretation.
Biological background
In addition, this cell line can be used in neuronal co-culture studies to simulate conditions in the brain. Upon stimulation with cytokines such as IL-1β, TNF-α and IFN-γ, these cells show up-regulated NOS-2 and COX-2 mRNA expression and release various inflammatory mediators. This cell line has a stable star-shape morphology and expresses immature astrocyte markers such as nestin and CD44, indicating that the cells are of the early-stage astrocyte precursor phenotype. Furthermore, they are capable of converting glutamate via glutamine synthase to glutamine, which is a characteristic of GFAP-negative astrocytes. Donor/background information provided for this product: Balb/c Mouse, Cerebral Cortex.
Research relevance and current trends
- Cultured cell-line models remain central to in vitro studies of phenotype, signaling, and pathway regulation under controlled conditions.
- Researchers commonly compare morphology, growth rate, and marker expression across media formulations, treatments, or time courses.
- Interpretation is generally strengthened by using matched controls, consistent passage handling, and appropriate culture surfaces.
Common research applications
- Neurobiology-focused studies of growth state, differentiation-associated morphology, and cell signaling changes in culture.
- Cell-based assays that compare experimental perturbations across defined media and substrate conditions.
- Phenotype tracking using morphology, marker expression, or reporter output where applicable.
Changes in morphology, growth rate, viability, or reporter signal are typically interpreted together with passage history, culture matrix, and the specified growth conditions for the model.
Notes for experimental interpretation
- Morphology, doubling behavior, and reporter or marker output can shift with passage number, substrate choice, and medium composition; these variables should be recorded alongside experimental readouts.
- Matched controls such as parental cells, untreated cultures, or parallel cultures maintained under identical conditions help distinguish background effects from biology of interest.
Culture and product details
- Growth Conditions: For optimal cell culture, we recommend using PriCoat™ T25 Flasks (G299) or coating your preferred vessels with Applied Cell Extracellular Matrix (G422). PriGrow III (TM003) + 10% FBS(Regular*) + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂. *Do not heat-inactivate
- Seeding Density (cells/cm²): 5,000 - 10,000
- Thaw cells quickly in a 37°C water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination.
- Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions.
- Transfer the cell suspension into a 15ml sterile conical tube containing 5ml of pre-warmed, complete growth media. Centrifuge cells at 125xg for 5 minutes.
- Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media and dispense into a T25 culture flask.
- Incubate the cells at the recommended conditions.
- Allow cells to recover and attach over the next 24-48 hours. Once cells have attached, change media every 2-3 days, or as required.
- Aspirate the culture media, and add 2-3ml of pre-warmed 0.25% Trypsin-EDTA to the culture vessel.
- Observe the cells under a microscope to confirm detachment (typically within 2-10 minutes). Cells that are difficult to detach can be put in 37°C, for several minutes to facilitate detachment.
- Neutralize Trypsin-EDTA by adding an equal volume of the complete growth media into the culture vessel.
- Transfer the culture suspension into a sterile centrifuge tube, and centrifuge at 125xg for 5 minutes. The actual centrifuge duration and speed may vary depending on the cell type.
- Aspirate the supernatant, and re-suspend the pellet with pre-warmed fresh complete growth media. Add appropriate aliquots of the cell suspension to new culture vessels, as desired.
- Incubate the cells at the recommended conditions.

How many times can cells divide?
Primary cells have a limited lifespan and will undergo a finite number of population doublings before entering senescence. The exact number varies by cell type and culture conditions.
Immortalized cell lines are capable of extended or indefinite proliferation under proper culture conditions, although growth characteristics may vary between lines.
Do I need Applied Cell Extracellular Matrix (G422) if I am using PriCoat™ flasks?
