Safety and efficacy of G-CSF mobilization and collection of autologous peripheral blood stem cells in children with cerebral palsy.

We hypothesized that mobilized peripheral blood stem cells (PBSCs) could be useful for treating neurological impairments and therefore assessed the safety of administering G-CSF followed by collecting PBSC in children with cerebral palsy (CP). G-CSF (10 μg/kg/day) was administered subcutaneously for 5 days, and apheresis was performed to collect PBSC via central venous catheter. G-CSF-related events occurred in 3 patients (fever in 2, irritability in 1). No catheter-related complications were reported. None of the patients needed platelet transfusion or calcium replacement during apheresis. Mobilization with G-CSF followed by PBSC collection appears to be safe and feasible in CP children.
