SNU-398 Cell Line

General Information
Organism Homo sapiens, human
Cell Line Description SNU-398 was established by Park et al. in 1990. This cell line was derived from primary hepatocellular carcinoma (HCC) tissue obtained from a 42-year-old Korean male patient. The patient had previously undergone treatment for a Hepatitis B virus (HBV) infection. SNU-398 cells exhibit an epithelial-like morphology and have been confirmed to harbor integrated HBV DNA sequences. Characterized by high motility and invasiveness, this cell line frequently serves as a representative model for liver cancer studies featuring mesenchymal characteristics (EMT); it is widely utilized to investigate the regulation of liver cancer cell growth, signal transduction pathways, HBV-mediated oncogenic mechanisms, and the evaluation of the efficacy of anticancer drugs.
Tissue Liver
Disease Hepatocellular Carcinoma (HCC)
Morphology Epithelial-like; grows as an adherent monolayer
Gender Male
Age 42 years
Product Format Frozen
Growth Mode Adherent
Biosafety Level 2 (Due to the presence of HBV DNA sequences)
Applications 1. Investigation into the pathogenesis of hepatocellular carcinoma (HCC) and tumor cell signal transduction
2. Study on the impact of hepatitis B virus (HBV) integration on the malignant transformation of hepatocytes
3. Investigation into the mechanisms of epithelial-mesenchymal transition (EMT), tumor migration, and invasion
4. In vitro screening of targeted agents and chemotherapeutic drugs for hepatocellular carcinoma
5. Establishment of human hepatocellular carcinoma xenograft mouse models
Shipped In Dry ice

Culture Conditions and Handling
Subculturing 1. Discard the old culture medium.
2. Wash the cell monolayer with Ca²⁺/Mg²⁺-free PBS.
3. Add 0.25% Trypsin – 0.53 mM EDTA and incubate at 37°C for approximately 5–10 minutes until the cells detach (as these cells adhere firmly, a longer incubation time may be required).
4. Add serum-containing complete medium to neutralize the enzymatic digestion, then gently pipette to mix thoroughly.
5. Seed the cells into new culture vessels at the appropriate ratio.
Medium Renewal 2 to 3 times per week
Subcultivation Ratio 1:3 to 1:6
Culture Conditions Atmosphere: Air, 95%; CO2, 5%; Temperature: 37°C
Cryopreservation 90% Complete growth medium + 10% DMSO
