GCSF Adjunct Therapy for Biliary Atresia

G-CSF is a glycoprotein produced by monocytes, fibroblasts, and endothelial cells. Filgrastim is a human granulocyte colony stimulating factor (G-CSF) produced by recombinant DNA technology with NEUPOGEN® as the Amgen Inc. trademark for filgrastim. G-CSF regulates the production, proliferation and differentiation of neutrophils and hematopoietic stem cell precursors within the bone marrow leading to dose-dependent increase in circulating neutrophils and hematopoietic stem cells in the blood. It is indicated to reduce the incidence of infection in patients with severe neutropenia, for neutrophil recovery in neutropenic patients with bone marrow depletion, to mobilize hematopoietic progenitor stem cell for collection by leukapheresis in hematopoietic stem cell transplantation.
