T cells originated from adoptively transferred splenocytes of donors cured by LTX-315 and inhibit the development of rTMSCs in naïve recipients. (A) Recipient rats were conditioned with total body irradiation (TBI) of 600 cGy one day before adoptive spleen cell transfer. Surviving rats were rechallenged twice after the initial LTX-315 treatment was used as a splenocyte donor. A group of rats (n = 15) received isolated spleen cells (30·106) from cured rats. Another group of rats (n = 6) were given T-cell depleted (TCD) splenocytes (18·106) from cured donors, whereas spleen cells (30·106) from naïve rats were transferred to rats in the control group (n = 5). One day after splenocyte transfer, animals were s.c. inoculated with 1·104 rTMSCs. The measurement of tumor development was tracked by bioluminescence imaging. (B) Representative images of recipient rats receiving spleen cells from cured donors (LTX-315), or from naïve donors (control) at designated days after tumor challenge. (C) Survival curve comparing tumor-free survival in animals receiving splenocytes from cured donors (solid line), TCD fraction of splenocytes (dashed line) or splenocytes from naïve donors (dotted line).
