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

objectiveHuman natural killer (NK) cell maturation involves the orderly acquisition of NK cell receptors. Our aim was to understand how stromal interactions and cytokines are important in this developmental process. MATERIALS AND

methodsHuman umbilical cord blood (UCB) CD34(+)/Lin(-)/CD38(-) cells were cultured on two murine stromal cell lines (AFT024 and EL08-1D2) in a switch culture to study NK cell development.

resultsWhen human progenitors were cultured on AFT024 with interleukin (IL)-3 and Flt3 ligand (Flt3L) in the absence of interleukin (IL)-15, NK cell differentiation occurred, albeit at low frequency. These conditions favored the accumulation of CD56(-) NK cell precursors (CD34(+)CD7(-), CD34(+)CD7(+), and CD34(-)CD7(+) cells), which are populations rare in adult blood but abundant in fresh UCB. In secondary culture, addition of IL-3 or IL-3 + Flt3L to IL-15 increased the absolute number of CD56(+) NK cells from precursors and the acquisition of CD94 and killer immunoglobulin-like receptors (KIR). To further explore the microenvironment in early NK cell maturation, a cell line derived from murine embryonic liver (EL08-1D2) was studied. NK cell development and KIR acquisition was superior with EL08-1D2, which supported the differentiation of NK cell precursors, NK cell commitment, and proliferation.

conclusionAlthough the earliest events in NK cell maturation do not require exogenous human IL-15, it is required at a later stage of NK cell commitment. At a minimum, murine stroma, IL-3, and Flt3L are required to recapitulate early NK cell development and differentiation into distinct NK cell precursors. EL08-1D2 induces KIR acquisition suggesting that extrinsic signals in NK cell development are conserved between mouse and man.
