MCA-205-OVA, MCA-205-E1A-Δp300-OVA and MCA-205-E1A-OVA tumor cells elicited similar <i>in vivo</i> OVA-specific cytotoxic T cell responses.

<p><b>A</b>) Mice were injected with 1×10⁶ live MCA-205, MCA-205-OVA, MCA-205-E1A-Δp300-OVA, or MCA-205-E1A-OVA tumor cells in the flank s.c. and an <i>in vivo</i> CTL assay against OVA pulsed splenocytes was performed seven days later. Data shown is the mean ± SEM from three experiments, with six mice per group. Data were analyzed by ANOVA followed by Tukey's HSD post hoc analyses. **, p<.01; ***, p<.001.
