Diabetes Limits Stem Cell Mobilization Following G-CSF but Not Plerixafor.

ABSTRACT: Previous studies suggest that diabetes impairs hematopoietic stem cell (HSC) mobilization in response to granulocyte colony-stimulating factor (G-CSF). In this study, we tested whether the CXCR4 antagonist plerixafor, differently from G-CSF, is effective in mobilizing HSCs in patients with diabetes. In a prospective study, individuals with and without diabetes (n = 10/group) were administered plerixafor to compare CD34(+) HSC mobilization; plerixafor was equally able to mobilize CD34(+) HSCs in the two groups, whereas in historical data, G-CSF was less effective in patients with diabetes. In a retrospective autologous transplantation study conducted on 706 patients, diabetes was associated with poorer mobilization in patients who received G-CSF with/without chemotherapy, whereas it was not
