Abstract

V originále

Existing experimental studies of the effect of sympathetic nerve fibers on bone marrow cells are based on the systemic administration of neurotoxic 6-hydroxydopamine. The method of global chemical sympathectomy has some serious disadvantages and could lead to questionable results. We describe a new method of local chemical sympathectomy of rat femoral bone marrow using guanethidine (Ismelin) delivery using an osmotic mini pump. Local guanethidine treatment for 14 days led to complete elimination of sympathetic fibers in femoral bone marrow in contrast to bone marrow of contralateral or naive femurs. Ablation of sympathetic fibers was associated with a loss of rat endothelial cell marker (RECA) indicating immunophenotype changes in blood vessel endothelial cells, but no significant effect of guanethidine was found on the survival of endothelial cells and mesenchymal stem cells in vitro. Moreover, local guanethidine treatment also elicited a significant reduction of Nestin +/SDF1 + mesenchymal stem cells and c-Kit +/CD90 + hematopoietic stem cells in femoral bone marrow. Tissue-specific chemical sympathectomy of rat bone marrow by guanethidine overcomes some of the drawbacks of systemic administration of neurotoxic compounds like 6-hydroxydopamine and delivers unequivocal evidence on the effects of sympathetic innervation on the cell content of bone marrow.
