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

Expansion of hematopoietic progenitor cells (HPC) in the presence of endothelium has been shown to result in grafts capable of restoring hematopoiesis in a myeloablated host. However, the use of xenogeneic endothelium or cell lines may carry risks in a clinical transplantation setting. We explored the feasibility of cord blood progenitor cell expansion in vitro in an autologous coculture system using umbilical vein endothelial cells (HUVEC). CD34+ HPC and HUVEC were isolated from the same umbilical cord. For 3 days, HPC were maintained in serum-free medium supplemented with a single cytokine (SCF) or a cytokine combination (SCF, Flt3-ligand, IL-6). Meanwhile, adherent HUVEC cultures were established. After addition of VEGF and IL-1 at day 3, the cells were either added to HUVEC cultures or grown without endothelial cells for further 7 days. Total cells, CD34+ and clonogenic progenitors were significantly increased when coculture was compared to liquid culture. Long-term culture-initiating cells (LTC-IC) and cobble stone area-forming cells (CAFC, limiting dilution analysis) were detected more frequently after coculture with endothelial cells. Also precursors and mature myeloid cells were observed after expansion. We conclude that coculture with autologous HUVEC represents a feasable approach for ex vivo expansion of cord blood HPC.
