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:$ A N# z0 V, M8 U. b
1.The impact of UM171 on LT-HSC was preserved at 30 weeks posttransplantation.时间足够的长。
7 M" |- f, `. A. ]' F0 G2.a slight augmentation in myeloid cell output, a phenomenon recently described with normal unexpanded cells9 T u( M. ~9 X8 K% N9 c( U
3.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。7 j$ `. |: F. H% C7 o- ?7 J: v
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。
