One recent study of serum SCF levels found significantly lower levels of SCF in fulminant hepatitis patients when compared to acute hepatitis patients and controls, and that these decreased levels were associated with poorer prognosis; the authors of this manuscript hypothesized that impaired SCF production in oval cells and bone marrow cells may be associated with poor regeneration of liver cells [64]. The gene discussed is KITLG; the disease is Acute hepatitis.
