Median MNC-subset counts in recipients of marrow and blood stem cells on about day 30, 80, 180, and 365 after transplantation.

Gray circles indicate marrow; black triangles, stem cells. Error bars indicate the 25th to 75th percentiles. Stars indicate a significant difference (P < .05). Normal values are shown as horizontal lines (thick solid line for the 10th and 90th percentiles and broken line for the median). Days after transplantation are shown on all x-axes. On all y-axes, values for cell counts are per microliter. The numbers of marrow recipients and blood stem cell recipients studied were 43 and 45, respectively, on day 30; 40 and 40 on day 80; 29 and 26 on day 180; and 25 and 30 on day 365.
