白藜芦醇是一种植物来源的多酚,已显示出对许多疾病的保护作用,包括几种类型的癌症和其他与年龄相关的疾病以及在培养细胞和/或动物模型中的血液疾病。然而,白藜芦醇是否对正常的血液干细胞有任何特定的影响仍不清楚。在这里,我们表明,白藜芦醇治疗三周增加了正常骨髓造血干细胞(HSC)的频率和总数,而不影响它们的竞争性再繁殖能力。此外,我们还发现白藜芦醇在体内增强了骨髓多能祖细胞的能力。这些结果对造血干细胞和祖细胞(HSPC)疾病以及骨髓移植环境都有治疗价值。
Resveratrol is a plant-derived polyphenol that has shown protective effects against many disorders including, several types of cancers and other age-associated diseases as well as blood disorders in cultured cells and/or animal models. However, whether resveratrol has any impact specifically on normal blood stem cells remains unknown. Here we show that a three-week treatment of resveratrol increases the frequency and total numbers of normal bone marrow hematopoietic stem cells (HSC) without any impact on their competitive repopulation capacity. In addition, we show that resveratrol enhances the bone marrow multipotent progenitor capacity in vivo. These results have therapeutic value for disorders of hematopoietic stem and progenitor cells (HSPC) as well as for bone marrow transplantation settings.
