From: Release of volatile organic compounds (VOCs) from the lung cancer cell line CALU-1 in vitro

Comparison of VOCs concentrations present at higher concentration in the headspace of CALU-1 cells in culture (blue columns) as compared to medium control (red columns) after 18 h of incubation. Presented are average concentrations (n = 3) with standard deviations. Significant differences are labeled with asterisks.
