<p>Pig insulin levels were measured 4 wk after transplantation of E42 and E56 pig pancreas into NOD-SCID mice in the absence (black bars) and presence (grey bars) of 80 × 10<sup>6</sup> adoptively transferred hu-PBMCs infused into the grafted mice 1–3 d after transplant. Four experiments were carried out, each comparing pig insulin levels secreted by the grafts from two gestational time points. The bars represent average ± standard deviation pig insulin levels measured in all experiments. The number of grafted NOD-SCID mice without and with hu-PBMCs, respectively, was as follows: 19 and 17 for E42, and 15 and 14 for E56.
