粒细胞集落刺激因子(G-CSF)动员的外周血造血祖细胞(HPC)的使用已在很大程度上取代骨髓(BM)作为自体和同种异体细胞移植的干细胞来源。单独使用G-CSF时,高达35%的患者无法动员足够数量的CD 34细胞/kg,以确保成功和一致的多谱系移植和持续的造血恢复。为此,正在进行研究,以确定新的药物或组合,这将导致最有效和最高效的干细胞动员策略,特别是在那些有动员失败风险的患者中。我们描述了既定的代理商和新的战略在不同的发展阶段。后者包括但不限于靶向SDF-1/CXCR 4轴的药物、S1 P激动剂、VCAM/VLA-4抑制剂、甲状旁腺激素、蛋白体抑制剂、Groβ和稳定HIF的药剂。虽然没有一种新型药物在临床实践中在HPC动员中发挥既定作用,但许多探索这些新途径的早期研究显示出有希望的结果,值得进一步研究。
Use of granulocyte colony stimulating factor (G-CSF)–mobilized peripheral blood hematopoietic progenitor cells (HPC) has largely replaced bone marrow (BM) as a source of stem cells for both autologous and allogeneic cell transplantation. With G-CSF alone, up to 35% of patients are unable to mobilize sufficient numbers of CD34 cells/kg to ensure successful and consistent multi-lineage engraftment and sustained hematopoietic recovery. To this end, research is ongoing to identify new agents or combinations which will lead to the most effective and efficient stem cell mobilization strategies, especially in those patients who are at risk for mobilization failure. We describe both established agents and novel strategies at various stages of development. The latter include but are not limited to drugs that target the SDF-1/CXCR4 axis, S1P agonists, VCAM/VLA-4 inhibitors, parathyroid hormone, proteosome inhibitors, Groβ, and agents that stabilize HIF. While none of the novel agents have yet gained an established role in HPC mobilization in clinical practice, many early studies exploring these new pathways show promising results and warrant further investigation.
