Abstract

Hepatocyte transplantation has been proposed as a technique for bridging patients to whole-organ transplantation, for providing metabolic support during liver failure, and for replacing whole-organ transplantation in certain metabolic liver diseases. Assessment of hepatocyte engraftment has been difficult to measure, and the degree of engraftment needed to correct various liver disorders is still unknown. A sensitive, simple, and specific method of monitoring engraftment of transplanted hepatocytes for the purpose of bridging human liver failure to native regeneration using short tandem repeats (STRs) was evaluated. The analytical sensitivity of the test was evaluated using DNA mixing curves and established as 0.5% (percentage of donor DNA/recipient DNA). Sex-matched and mismatched cases were included during the validation. The clinical evaluation of the assay was performed using liver samples from two patients who underwent hepatocyte transplantation. We concluded from this study that the AmpFLSTR® Profiler Plus™ PCR Amplification Kit, a well-established technique in forensic medicine, is specific, sensitive, and a reproducible assay for measurement of engraftment after hepatocyte transplantation in both sex-matched and sex-mismatched cases.
