Liver, pancreas and kidney data show no organ toxicity after the intrabronchial infusion of adult stem cells during endotoxin-induced ARDS. To measure liver function (A), protein levels of alanine aminotransferase, alkaline phosphatase and aspartate aminotransferase were measured in plasma. Amylase, glucose and lipase plasma levels were quantitated to evaluate pancreatic function (B) and creatinine and blood urea nitrogen for kidney function (C). All the values are within normal ranges. The control group (no treatment) is represented by dotted lines and the experimental group (receiving stem cells) by solid black lines. ARDS, acute respiratory distress syndrome.
