Stem Cell Applications in Biliary Atresia Patients

UC-MSC transplantation will be administered twice to each patient in the study group via the hepatic artery: the first transplantation will be performed post-surgery at the beginning, and the second one will be performed 6 months later, with a dose of 1 million UC-MSC/kg.

In this group, UC-MSC will not be administered. This group serves as a passive control. The standard treatments that are routinely provided to these patients will continue to be administered.
