Protocol 3: Cytotoxicity of the sequential treatment with MTA followed by 1 h of GEM in vitro

Subconfluent monolayers were treated with MTA at 0, 0.3, or 1 μm for 24 h, followed by GEM for 1 h. Data are expressed as percentage of colonies formed relative to untreated samples. Values are averaged from three independent experiments ± SE.
