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

There are concepts in science that need time to overcome initial disbelief before finally arriving at the moment when they are embraced by the research community. One of these concepts is the biological meaning of the small, spheroidal vesicles released from cells, which are described in the literature as microparticles, microvesicles, or exosomes. In the beginning, this research was difficult, as it was hard to distinguish these small vesicles from cell debris or apoptotic bodies. However, they may represent the first language of cell-cell communication, which existed before a more specific intercellular cross-talk between ligands and receptors emerged during evolution. In this review article, we will use the term "extracellular microvesicles" (ExMVs) to refer to these small spheroidal blebs of different sizes surrounded by a lipid layer of membrane. We have accepted an invitation from the Editor-in-Chief to write this review in observance of the 20th anniversary of the 2001 ASH Meeting when our team demonstrated that, by horizontal transfer of several bioactive molecules, including mRNA species and proteins, ExMVs harvested from embryonic stem cells could modify hematopoietic stem/progenitor cells and expand them ex vivo. Interestingly, the result that moved ExMV research forward was published first in 2005 in Leukemia, having been previously rejected by other major scientific journals out of simple disbelief. Therefore, the best judge of a new concept is the passage of time, although the speed of its adoption is aided by perseverance and confidence in one's own data. In this perspective article, we will provide a brief update on the current status of, hopes for, and likely future of ExMV research as well as therapeutic and diagnostic applications, with a special emphasis on hematopoiesis.
