BMMCs infusion is feasible and practical in a clinical setting. In vivo tracking of labelled cells demonstrated that the hepatic artery route successfully delivered BMMCs to the liver. The early improvement of laboratory indices of liver function should be interpreted with caution, because this study was not designed to evaluate efficacy. The median Model for End-Stage Liver Disease score had not deteriorated 1 year later. The occurrence of a graft-versus-host disease-like phenomenon highlights the importance of sustained vigilance even when giving autologous cells. Controlled studies are needed to determine whether BMMCs infusion affects HCC development in cirrhosis.
