CSF3 and Hepatic fibrosis: Bone marrow (BM) cells injected into mice with chronic liver injury resulted in a reduction in hepatic fibrosis and an improvement in serum albumin,7 while mobilisation of BM cells by injection of GCSF reduced the severity of liver injury and improved survival in both acute and chronic models of liver injury.8 However, other studies have shown either no beneficial effect of BM cell injections9 or even a worsening of hepatic fibrosis after bone marrow cell injection.10
