NOD BMCs form CFU-S colonies in both allogeneic and syngeneic recipients. BMCs from NOD or B10.BR mice were isolated and administered to either NOD or B10.BR (BR) recipient mice 6 hours after receiving 950 cGy TBI. Day-12 splenic colonies were enumerated. Data are the mean and standard deviation from 3 separate experiments. P values were determined using a 2-tailed Student t test with the assumption of equal variance. n.a. indicates not applicable.
