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

To study molecular events involved in B lymphocyte development and V(D)J rearrangement, we have established an efficient system for the differentiation of embryonic stem (ES) cells into mature Ig-secreting B lymphocytes. Here, we show that B lineage cells generated in vitro from ES cells are functionally analogous to normal fetal liver-derived or bone marrow-derived B lineage cells at three important developmental stages: first, they respond to Flt-3 ligand during an early lymphopoietic progenitor stage; second, they become targets for Abelson murine leukemia virus (A-MuLV) infection at a pre-B cell stage; third, they secrete Ig upon stimulation with lipopolysaccharide at a mature mitogen-responsive stage. Moreover, the ES cell-derived A-MuLV-transformed pre-B (EAB) cells are phenotypically and functionally indistinguishable from standard A-MuLV-transformed pre-B cells derived from infection of mouse fetal liver or bone marrow. Notably, EAB cells possess functional V(D)J recombinase activity. In particular, the generation of A-MuLV transformants from ES cells will provide an advantageous system to investigate genetic modifications that will help to elucidate molecular mechanisms in V(D)J recombination and in A-MuLV-mediated transformation.
