Improved hematopoietic differentiation of mouse embryonic stem cells through manipulation of the RNA binding protein ARS2.

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
The RNA binding protein ARS2 is highly expressed in hematopoietic progenitor populations and is required for adult hematopoiesis. Recent molecular studies found that ARS2 coordinates interactions between nascent RNA polymerase II transcripts and downstream RNA processing machineries, yet how such interactions influence hematopoiesis remains largely unknown. Techniques to differentiate embryonic stem cells (ESC) to hematopoietic progenitor cells (HPC) and mature blood cells have increased molecular understanding of hematopoiesis. Taking such an in vitro approach to examine the influence of ARS2 on hematopoiesis, we found that ARS2 suppresses expression of some HSC signature genes and differentiation of ESC to a HPC population (CSMD-HPC) identified by markers expressed on bone marrow resident hematopoietic stem cells. In line with ARS2's ability to promote proliferation of cultured cells, ARS2 knockout ESC showed limited expansion and yielded less CSMD-HPC than wild-type ESC. In contrast, transient ARS2 knockdown led to doubling the number of CSMD-HPC generated per ESC without affecting further differentiation into mature T-cells. Overall, data indicate that ARS2 negatively regulates early hematopoietic differentiation of ESC, in stark contrast to its supportive role in adult hematopoiesis. Consequently, manipulation of ARS2 expression and/or function has potential utility in hematopoietic cell engineering and regenerative medicine.
