Lineage-specific chimerism analyses from 3 separate patients following reduced-intensity transplantation using microsatellite polymerase chain reaction (PCR).

Three separate patterns of chimerism are shown. The left panel shows full donor chimerism following transplant, the center panel indicates mixed chimerism in all lineages, and the right panel shows mixed chimeras in the T-cell lineage alone.Reprinted with permission from Kottaridis P, Milligan DW, Chopra R, et al.
