To further explore whether MerTK plays an indispensable role in the immune-modulating behavior of MSCs/DMSCs/PSLs for ConA-induced liver injury, we used MerTK-knockout mice (MerTK−/− group) to evaluate the therapeutic effects and B6/129 mice with the same genotype background were used as control (wild-type (WT) group). The gene discussed is MERTK; the disease is injury.
