Fig 1: HNF-4a-MSCs inhibited Kupffer cell-associated inflammation. a Concentrations of the inflammatory factors TNF-a, IFN-? and IL-6 were detected in mouse serum on the sixth week using a Bio-plex assay. b Expression of ALB was detected using IHC (× 320). c The Kupffer cell marker CD68 was detected in mouse livers using IHC (× 200). d Quantification of panel c. Three fields of view were selected for each group to count the CD68-positive cells. The mean of the three fields was used to represent the CD68+ cells for each group. (Five mice were used in each group. The data are represented as the mean ± S.D.) Scale bars, 100 µm
