MDLN cells were incubated with two human melanoma cell lines (A375 and SK-Mel-28), one human breast cancer line (MDA-231) and one human brain cancer line (U-87). Baseline apoptosis for A375, Sk-mel-28, MDA-231, and U-87 were 8.0%, 9.0%, 7.7%, 7.3%, respectively. Addition of MDLN cells increased apoptosis over baseline by 27.1%, 29.1%, 14.6%, 14.8%, respectively. Increase in apoptosis for A375 and Sk-mel-28 were statistically significant (p<0.001) while increases in MDA-231 and U-87 were not (p=0.25 and p=0.18, respectively). Error bars indicate 95% CI. N=9.
