a Albumin release by liver MPS in control and fibrotic condition for 144 h. A sudden decrease in albumin concentration was noted after applying a fibrosis stimulus (TGF-β1) at 72 h (data presented as mean ± SD, bar column with cross lines representing the control values). b Urea production by liver MPS in control and fibrotic condition for 144 h. TGF-β1 stimulation for fibrosis induction at 72 h reduced the urea release by the hepatocytes [data presented as mean ± standard deviation (SD) bar column without cross lines representing the control values]
