Table 1 Characteristics of the included studies

Ref.	Year	Country	Assessment of purity	Type of infused cells and volume	Infused cells (n)	Patients and disease etiology (n)	Frequency of stem cell transfusions	The route of transfusion

¹This patient developed progressive renal failure, and went on to develop type 1 hepatorenal syndrome and died of liver failure. MSCs: Mesenchymal stem cells; FACS: Florescence-assisted cell sorting; NA: Not available; HBV: Hepatitis B virus; AIH: Autoimmune liver disease; PBC: Primary biliary cirrhosis; HCV: Hepatitis C virus.
