BM, spleen, and thymus were harvested from engrafted NOD/SCID/IL2rγnull mice at 3 months after transplantation. Total cell numbers in BM and thymus represent the cells harvested from 2 femurs for BM and those harvested from a hemilobe for thymus. Recipients 1, 2, 4, and 5 received transplants of 1 × 105 Lin-CD34+ cells. Recipients 6, 7, and 8 received transplants of 2 × 104 Lin-CD34+CD38- cells. NE indicates not examined.
