' u7 A9 \2 l% q& [赞,这篇文章报道的时候是说真正意义上的造血干细胞扩增,我理解他定义为真正意义体现在以下三个方面:
4 y- y" A; ~6 w. H0 f! |: Q* X1.The impact of UM171 on LT-HSC was preserved at 30 weeks posttransplantation.时间足够的长。
5 B) { p; u3 Y: b, K2 F" [/ m$ y2.a slight augmentation in myeloid cell output, a phenomenon recently described with normal unexpanded cells
6 D5 Y* B1 [0 e9 ?! S! _ B$ b7 T3.The molecular and cellular mechanisms underlying this effect of UM171 on expanding LT-HSCs that show a lymphoid-deficient differentiation pattern are of interest given previous studies of a similar self-perpetuating LT-HSC subset in mice whose prominence is increased in the bone marrow as soon as HSCs begin to migrate from the fetal liver to that site 。2和3表明um171处理后的细胞具有更多原始细胞的分化特征。4 K0 X) v! j. G* n3 d+ M
但是看完全文我理解的是仅有UM171是不够的,因为分化的缺失导致免疫重建延迟,作者的意思是SR1可以导致更多的祖细胞扩增,这样两者结合是不是效果更好?哎,文章写的生涩难懂,可能是我水平不够。& b/ ~6 s6 T- Q# X
