Experimental design of BM-MSCs injection. Hepatic fibrosis was induced in Sprague-Dawley rats by intraperitoneal (i.p.) injections of TAA (300 mg/kg) twice a week for 12 weeks. The BM-MSCs were injected directly into the right liver lobe twice, at 6 and 8 weeks during the 12-week TAA administration.
