1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The discovery of novel hematopoietic stem cell (HSC) surface markers can enhance understanding of HSC identity and function. We have discovered a population of primitive bone marrow (BM) HSCs distinguished by their expression of the heparan sulfate proteoglycan Syndecan-2, which serves as both a marker and a regulator of HSC function. Syndecan-2 expression was increased 10-fold in CD150+CD48-CD34-c-Kit+Sca-1+Lineage- cells (long-term HSCs [LT-HSCs]) compared with differentiated hematopoietic cells. Isolation of BM cells based solely on syndecan-2 surface expression produced a 24-fold enrichment for LT-HSCs and sixfold enrichment for α-catulin+c-kit+ HSCs, and yielded HSCs with superior in vivo repopulating capacity compared with CD150+ cells. Competitive repopulation assays revealed the HSC frequency to be 17-fold higher in syndecan-2+CD34-KSL cells compared with syndecan-2-CD34-KSL cells and indistinguishable from CD150+CD34-KSL cells. Syndecan-2 expression also identified nearly all repopulating HSCs within the CD150+CD34-KSL population. Mechanistically, syndecan-2 regulates HSC repopulating capacity through control of expression of Cdkn1c (p57) and HSC quiescence. Loss of syndecan-2 expression caused increased HSC cell cycle entry, downregulation of Cdkn1c, and loss of HSC long-term repopulating capacity. Syndecan-2 is a novel marker of HSCs that regulates HSC repopulating capacity via control of HSC quiescence.
