Relative number of vital MB cells after 6-day single drug treatment. The number of vital cells was examined by trypan blue exclusion assay in three MB cell lines after 6-day treatment with: a) 5-aza-dC, b) VPA, c) SAHA, d) ATRA, e) ABC, f) RES. Five distinct drug concentrations were applied and values are normalized to the initial-seeded cell number (dashed line). For each cell line one experiment was performed
