Granulocyte-colony stimulating factor for mobilizing bone marrow stem cells in the sub acute stroke. How safe is the use of granulocyte-colony stimulating factor in sub-acute stroke? Is this stem cell trial of recovery enhancement beneficial?

Efforts are being made to develop neuroprotective agents for recovery and prevention of further deterioration of brain tissues in patient with stroke.Granulocyte-colony stimulating factor (GCSF) is a glycoprotein hormone encoded by a single gene located on chromosome 17q 11-22. It functions in the regulation of granulopoiesis& terminal maturation of neutrophills. It is being used for the treatment of neutropenia for the production of CD34+ haematopoietic stem cell (HSC) for bone marrow transplant patients. Neuroprotective effect of GCSF is being studied in various experimental studies but its mechanism of action is not well understood and appears to be multimodal.
