Methanol stimulates the colony-formation rate in a human hepatoma cell line (HLE).
Effects of methanol on colony-formation of human hepatoma cells were investigated. Among five human hepatoma cell lines (Hep G2, HLE, HuH-6, HuH-7, and PLC/PRF/5), only HLE cells showed enhanced colony formation due to methanol. The effective concentrations of methanol were around 1%. The enhancement occurred in a greater degree when the cells were seeded in the culture medium containing methanol than when methanol was added 24h after the cells were seeded. Methanol itself, however, did not enhance the cell proliferation.
