Abstract

Age related changes in activity of hematopoietic progenitor cells led us to investigate the possibility that glucan supplementation might overcome this suppression. In our study, we focused on differences of these cells in young (8 weeks old) and old (18 months old) mice after supplementation of yeast-derived insoluble glucan. Our results showed significant differences in reconstitution ability of progenitor cells as well as changes in level of stromal cell-derived factor 1α between young and old mice exist and can be partly restored by glucan supplementation.

补充葡聚糖对老年造血祖细胞的影响
年龄相关的造血祖细胞活性变化使我们研究补充葡聚糖可能克服这种抑制的可能性。在我们的研究中,我们重点研究了在补充酵母来源的不溶性葡聚糖后,幼龄(8周)和老年(18个月)小鼠中这些细胞的差异。我们的研究结果表明,在年轻和年老小鼠之间,祖细胞的重建能力和基质细胞衍生因子1α水平的变化存在显著差异,并且可以通过补充葡聚糖部分恢复。
