Human Liver Cancer-Associated Fibroblasts (CAFs) - Product Specifications
Quality Control & Characterization
Our Human Liver CAFs undergo rigorous quality testing to ensure research reliability. The cells demonstrate negative expression of endothelial (von Willebrand Factor/Factor VIII), epithelial (cytokeratin 18), and smooth muscle (α-SMA) markers, confirming fibroblast purity. All cultures test negative for microbial contamination (bacteria, yeast, fungi, and mycoplasma). The cells positively express characteristic CAF markers including FAP, PDGFR, Vimentin, PDPN, and CD70, with stable growth maintained for 3-5 passages at recommended 1:2 to 1:3 split ratios.
Research Applications
These primary liver CAFs are ideal for:
• Tumor microenvironment studies
• Cell-cell interaction and adhesion assays
• Molecular analysis (PCR, Western blot, immunoprecipitation)
• Cellular characterization (immunofluorescence, flow cytometry)
• Development of advanced liver cancer models
• Drug screening and therapeutic development
Cell Handling Protocol
Shipping & Storage
Shipped frozen on dry ice
Optimal storage:
Immediate culture recommended
Alternative: liquid nitrogen vapor phase
Avoid -70°C storage (reduces viability)
Thawing & Culture Initiation
Rapid thaw in 37°C water bath (≤2 minutes)
Surface sterilize with 70% ethanol
Centrifuge (125 × g, 5-10 min) to remove cryoprotectant
Resuspend in fresh CAF Growth Medium

Incubate at 37°C, 5% CO₂ (pre-equilibrate medium 15 min)
Subculture Procedure
Remove medium and rinse with PBS
Add 2-3 mL Cell Detachment Solution (5-15 min)
Neutralize with complete medium (6-8 mL)
Replate at 1:2 to 1:3 ratio in freshly coated flasks
Change medium every 3-4 days
Cryopreservation
Use complete growth medium with 5% DMSO
Store long-term in liquid nitrogen vapor phase
