Anti-tumor protection conferred by semi-allogeneic vaccines. The bar graph shows the average tumor weight per mouse and the standard deviation. Differences in tumor weight between mock-vaccinated mice (PBS) and mice vaccinated with semi-allogeneic cell hybrids (Vac) were statistically significant for both challenges: p-values were < 0.0001 and 0.0017 for the 2 × 10⁴ and the 3 × 10⁴ EL-4 lymphoma cells challenge, respectively.
