Eicosanoids have been implicated in the physiological regulation of hematopoiesis with pleiotropic effects on hematopoietic stem cells and various classes of lineage restricted progenitor cells. Herein we review the effects of eicosanoids on hematopoiesis, focusing on new findings implicating prostaglandin E(2) in enhancing hematopoietic stem cell engraftment by enhancing stem cell homing, survival and self-renewal. We also describe a role for cannabinoids in hematopoiesis. Lastly, we discuss the yin and yang of various eicosanoids in modulating hematopoietic stem and progenitor cell functions and summarize potential strategies to take advantage of these effects for therapeutic benefit for hematopoietic stem cell transplantation.
类二十烷酸在造血生理调节中发挥作用,对造血干细胞和各种谱系限制祖细胞具有多效性影响。在此,我们综述了类二十烷酸对造血的影响,重点介绍了前列腺素 E2 通过增强干细胞归巢、存活和自我更新来增强造血干细胞植入的新发现。我们还描述了大麻素在造血中的作用。最后,我们讨论了各种类二十烷酸在调节造血干细胞和祖细胞功能中的阴阳两面,并总结了利用这些作用治疗造血干细胞移植的潜在策略。
