Loss of endothelial-ARNT in adult mice contributes to dampened circulating proangiogenic cells and delayed wound healing.

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 recruitment and homing of circulating bone marrow-derived cells include endothelial progenitor cells (EPCs) that are critical to neovascularization and tissue regeneration of various vascular pathologies. We report here that conditional inactivation of hypoxia-inducible factor's (HIF) transcriptional activity in the endothelium of adult mice (Arnt(ΔiEC) mice) results in a disturbance of infiltrating cells, a hallmark of neoangiogenesis, during the early phases of wound healing. Cutaneous biopsy punches show distinct migration of CD31(+) cells into wounds of control mice by 36 hours. However, a significant decline in numbers of infiltrating cells with immature vascular markers, as well as decreased transcript levels of genes associated with their expression and recruitment, were identified in wounds of Arnt(ΔiEC) mice. Matrigel plug assays further confirmed neoangiogenic deficiencies alongside a reduction in numbers of proangiogenic progenitor cells from bone marrow and peripheral blood samples of recombinant vascular endothelial growth factor-treated Arnt(ΔiEC) mice. In addition to HIF's autocrine requirements in endothelial cells, our data implicate that extrinsic microenvironmental cues provided by endothelial HIF are pivotal for early migration of proangiogenic cells, including those involved in wound healing.
