In situ hybridization of femoral marrow sections. (a) Balb/c male control showing Y-chromosome specific signal (arrows). (b) Balb/c female control showing Y-chromosome negative cells. (c) Balb/c female transplant recipient 6 months after receiving 100 cGy and 40 × 106 Balb/c male marrow cells. (d) Same as (c) except excited with UV. The transplant resulted in 81% marrow chimerism as determined by Southern blot analysis. Arrows indicated positive marrow cells of donor origin. Scale bar for (a) through (d) = 30 μm.
