Abstract:
Chimerism is the unique state when cells from genetically different individuals coexist. Chimerism testing allows measuring the donor and recipient immune cell subsets in recipient blood and bone marrow following stem cell transplantation. Chimerism testing is the standard diagnostic test for monitoring engraftment dynamics and early relapse prediction in the recipient following stem cell transplantation. Chimerism testing is also helpful to detect graft-versus-host disease following liver transplantation. Herein, we describe a step-by-step procedure of an in-house-developed method assessing chimerism levels using fragment length analysis of short tandem repeats.
