CD14 and graft versus host disease: To validate that the 3rdHSC-iNKT cells ameliorate GvHD via the depletion of donor CD14+ myeloid cells in the xeno-GvHD model, we conducted another experiment wherein NSG mice received CD14+ myeloid cell-depleted PBMCs with or without the addition of 3rdHSC-iNKT cells (Figure 3D).
