关键是影响力大
影响因子比NATURE大的杂志还有不少,但影响力都不如SCIENCE 和NATURE

楼主跟此文作者是亲戚吗?

Top of pageAbstractHaematopoietic stem cell (HSC) niches, although proposed decades ago1, have only recently been identified as separate osteoblastic and vascular microenvironments2, 3, 4, 5, 6. Their interrelationships and interactions with HSCs in vivo remain largely unknown. Here we report the use of a newly developed ex vivo real-time imaging technology and immunoassaying to trace the homing of purified green-fluorescent-protein-expressing (GFP+) HSCs. We found that transplanted HSCs tended to home to the endosteum (an inner bone surface) in irradiated mice, but were randomly distributed and unstable in non-irradiated mice. Moreover, GFP+ HSCs were more frequently detected in the trabecular bone area compared with compact bone area, and this was validated by live imaging bioluminescence driven by the stem-cell-leukaemia (Scl) promoter–enhancer7. HSCs home to bone marrow through the vascular system. We found that the endosteum is well vascularized and that vasculature is frequently localized near N-cadherin+ pre-osteoblastic cells, a known niche component. By monitoring individual HSC behaviour using real-time imaging, we found that a portion of the homed HSCs underwent active division in the irradiated mice, coinciding with their expansion as measured by flow assay. Thus, in contrast to central marrow, the endosteum formed a special zone, which normally maintains HSCs but promotes their expansion in response to bone marrow damage.

在国外是认通讯作者的,通过文章的信息我们可以知道,通讯作者不是上海交大的,所以不能算是我们国家的文章,虽然第二通讯作者是华人(?),但是也不能算是我们国家的文章。目前在我们国家,能发高水品文章的还真不是很多,关键就是要看通讯作者。
