Stem cell factor is essential for preserving NOD/SCID reconstitution capacity of ex vivo expanded cord blood CD34(+) cells.

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.
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
objectivesStem cell factor (SCF) is essential in the haematopoietic stem cells (HSCs) niche, and is therefore used extensively in haematopoietic stem and progenitor cells (HSPCs) ex vivo expansion. However, in the literature, dose and schedule of SCF feeding varies widely. We previously proposed a novel SCF feeding regimen with proven effectiveness for HSPCs expansion; however, physiological function of expanded cells with this SCF feeding regimen required further research. MATERIALS AND
methodsCD34(+) cells were cultured with or without SCF supplementation in serum-free medium for 10 days. Expanded cells were transplanted into sublethally irradiated non-obese diabetic/severe combined immune-deficient (NOD/SCID) mice. Engraftment and multilineage reconstitution of transplanted cells were determined. Also, clonogenic potential of engrafted cells was analysed.
resultsCells, both cultured with and without SCF supplementation, successfully engrafted and reconstituted blood cell lineages in NOD/SCID mice. However, level of engraftment and multilineage reconstitution reduced when cells were expanded without SCF supplementation. Meanwhile, frequencies of colony-forming cells (CFCs) amongst bone marrow cells were higher in mice transplanted with CD34(+) cells expanded with SCF supplementation.
conclusionsReconstitution capacity reduced when CD34(+) cells were expanded without SCF supplementation, though this feeding regimen did not have any effect on cell expansion. This finding suggested that SCF was essential for preserving NOD/SCID reconstitution capacity of ex vivo expanded CD34(+) cells.
