4. Figure 3
Responsiveness of SD rat lymphocytes to ahMSC 7 days after injection of ahMSC (B, pooled peripheral blood from 3 syngenic rats; C, 1 individual rat) and with no previous exposure to ahMSC (A), as assayed by MLR. Experiments were performed in triplicate with a significance of P < .01. Mean ± SD.

5. Figure 4
ahMSC elicit a significant proliferative response when cultured with PBL from SD rats but not from RNU rats previously exposed to ahMSC (P < .01). Rat PBL (1 × 105) were cultured with 1 × 105 irradiated autologous lymphocytes in the absence (Bg, Background) or presence (MSC) of 1 × 104 ahMSC. Each bar depicts 1 experiment performed in triplicate. K, control animals; SD, PBL from SD rats 7 days post–cardiac injection of ahMSC; RNU, PBL from an athymic RNU rat 7 days post–cardiac injection of ahMSC. Mean ± SD.
