Figure 2: HGF-UCMSC treatment reduces hepatic damage in ALF mice. (a–d) Morphological analysis of the liver. (e–i) HE staining of the necrosis area in liver sections in ALF mice induced by 750 mg/kg acetaminophen. (j) Treatment with HGF-UCMSC and UCMSC significantly prolonged the survival of mice that received a lethal dose of Acetaminophen compared with nontreated animals.
