Multilineage engraftment analysis.

Multilineage engraftment was analyzed at 8 and 24 weeks after TBI and TCD BMT at 4 (A) or 8 (B) weeks of age. Donor lineage analysis for myeloid (Gr-1 and Mac-1) and lymphoid (CD3 and B220) markers is expressed as a percentage of the level of total donor chimerism. Controls consist of normal lineage composition in peripheral blood of naive B6Pep3b mice. Those levels denoted with an asterisk demonstrate no significant difference (P < .05) compared with controls.
