Overview
Chondrocytes in vivo produce and maintain the extracellular matrix of the cartilage. In vitro, chondrocytes after serial passages as a monolayer culture have been documented to lose their phenotypic markers and become de-differentiated. The product is supplied as frozen cells.
Key elements and design rationale
- Biological source: Human (H. sapiens)
- Tissue origin: Cartilage
- Growth properties: Adherent, multipolar
- Format: Frozen
- Seeding guidance: 10,000 - 20,000 cells/cm²
- Biosafety level: II
- Culture context: For optimal cell culture, we recommend using PriCoat™ T25 Flasks (G299) or coating your preferred vessels with Applied Cell Extracellular Matrix (G422). PriGrow X Series Medium (TM0020) + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂.
Chondrocytes maintain cartilage extracellular matrix and are commonly used to study differentiation state, matrix turnover, inflammatory response, and tissue-specific stress programs.
Research relevance and current trends
- Primary chondrocyte models are used to assess matrix-associated gene expression and inflammatory remodeling.
- Investigators frequently compare donor or tissue-context effects on phenotype stability in culture.
- 3D-adjacent and matrix-focused systems are often explored to preserve cartilage-relevant behavior.
Common research applications
- Measure matrix synthesis, catabolic markers, or inflammatory responses in cartilage-relevant assays.
- Study phenotype stability and signaling changes over time in culture.
- Use in matrix-rich or co-culture systems to evaluate tissue-context effects.
Product-specific data supplied for this listing
- 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 X Series Medium (TM0020) + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂.
- Seeding Density (cells/cm²): 10,000 - 20,000
Notes for experimental interpretation
- Primary cells can show donor-dependent and passage-dependent variation, so morphology, growth rate, and marker expression should be interpreted in the context of the specific lot and culture history.
- Attachment matrix, medium formulation, and gas conditions can materially influence phenotype maintenance and experimental readouts; use the recommended culture system where possible.
- Cryopreserved recovery conditions matter for viability and downstream behavior. We recommend using serum-free CryoGuard™ Freezing Media (TM078).
- 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.
