Overview
The temporomandibular joint (TMJ) is the jaw joint that hinges to allows complex movements related to eating and swallowing. TMJ disc tissue permits mandibular movement and its degeneration has been linked to many clinical pathologies related to joint function, including crepitus, arthritis and headaches.
Key elements and design rationale
- Model identity: Immortalized Mouse TMJ Disc Chondrocyte-Like Cells is supplied as an immortalized cell line derived from Mouse cartilage.
- Growth properties: Adherent, fibroblast
- 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 VIII Medium (TM018) + 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 cell fate, differentiation, and expansion studies. Donor/background information is available for contextual interpretation.
Biological background
TMJ disc tissue comprises of a complex matrix of cells with regional difference in morphology, including chondrocyte -like cells and fibroblast-like cells. This organization of cells allow for the dissipation of forces acting on the jaw joint. The immortalized mouse TMJ Disc cell line was derived from chondrocyte-like cells from a 12-week-old female mouse. These cells are designed to be suitable for cell-type specific studies on the physiology and progression of TMJ disc disorders. Characterization was conducted by Western blot, qRTPCR, and immunofluorescence.These cells demonstrate trilineage differentiation potential, with the ability to undergo adipocytic, osteoblastic, and chondrocytic differentiation under defined in vitro conditions (Park, Y et al., 2015). Donor/background information provided for this product: 12-week-old female mouse.
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
- Expansion and maintenance studies under defined growth conditions prior to downstream differentiation or phenotype analysis.
- Comparative experiments that examine changes in morphology, marker expression, or functional readouts over time.
- Assay development in culture systems where media composition and substrate selection influence interpretation.
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 VIII Medium (TM018) + 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 5-7 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.
- 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?
