CPS treatment confers protection against pancreatic tumor re-challenge. (A) Treatment schematic outlining the treatment used for generating long-term survival. (B) One week after injection of 1.0 × 106 Pan02 cells i.p. mice were treated with CPS using a five-dose (n = 52) treatment schedule as outlined in Fig. 1A and survival was monitored. (C) 225 d after initial tumor inoculation, CPS-treated survivors (n = 5) or age-matched naive mice (n = 5) were re-challenged with 1.0 × 106 Pan02 cells and survival was monitored. **= p < 0.01, ***= p < 0.001.
