BCLAF1 restrains stress responses in hematopoietic stem cells to support expansion and repopulation.

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
abstractHematopoietic stem cells (HSCs) rapidly expand during fetal development and after stress. Here, we identify B-cell lymphoma-2-associated factor 1 (BCLAF1) as a regulator of HSC repopulation activity, with roles in the expansion of fetal HSCs and hematopoietic reconstitution after stem cell transplantation. Using mice with hematopoietic-specific and inducible deletion of Bclaf1, we find that BCLAF1 promotes fetal HSC development but is dispensable for the maintenance of adult HSCs at steady state. Loss of BCLAF1 in either fetal or adult HSCs significantly impairs their self-renewal and multilineage reconstitution activity after stem cell transplantation. Single-cell RNA sequencing of fetal hematopoietic progenitors reveals that loss of BCLAF1 reduces long-term HSCs and restrains the expression of stress response genes. BCLAF1 associates with chromatin throughout the genome of fetal and adult hematopoietic cells, likely through indirect mechanisms, to regulate transcriptional programs. These results establish a novel function for the transcriptional regulator BCLAF1 in limiting stress responses in HSCs, thereby preserving HSC development during embryogenesis and repopulation function after stem cell transplant.
