Furthermore, MSC implantation significantly improved serum TGF‐β levels but decreased the serum levels of IL‐17, TNF‐α and IL‐6 after transplantation in vivo in HBV‐related liver cirrhosis patients.1 Zhang et al enrolled patients with HBV‐induced decompensated liver cirrhosis, treated them with MSC transplantation and followed up to assess the long‐term efficacy. Here, TGFB1 is linked to cirrhosis of liver.
