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

backgroundHuman adipose-derived stem cells (hADSCs) have gained attention lately because of their ease of harvesting and ability to be substantially multiplied in laboratory cultures. Stem cells are usually cultured under atmospheric conditions; however, preconditioning stem cells under hypoxic conditions seems beneficial.

aimThis systematic review aims to investigate the effect of hypoxia preconditioning and its impact on the proliferation and angiogenic capacity of the hADSCs.

methodsWe performed a systematic review by searching PubMed, Scopus, Embase, and Google Scholar databases from all years through March 22, 2021, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Medical Subject Headings terms "adipose-derived stem cell," "Hypoxia," "cell proliferation," and "angiogenesis" guided our search. Only articles written in English using experimental models comparing a preconditioned group against a control group of hADSCs with data on proliferation and angiogenic capacity were included.

resultsOur search yielded a total of 321 articles. 11 articles met our inclusion criteria and were ultimately included in this review. Two studies induced hypoxia using hypoxia-inducible factor-1 alpha stabilizing agents, while nine reached hypoxia by changing oxygen tension conditions around the cells. Four articles conducted

conclusionIn this review, we found evidence to support hypoxia preconditioning of hADSCs before implantation. Benefits include enhanced cell proliferation with a faster population doubling rate and increased secretion of multiple angiogenic growth factors, enhancing angiogenesis capacity. RELEVANCE FOR PATIENTS: Although regenerative therapy is a promising field of study and treatment in medicine, much is still unknown. The potential for angiogenic therapeutics with stem cells is high, but more so, if we discover ways to enhance their natural angiogenic properties. Procedures and pathologies alike require the assistance of angiogenic treatments to improve outcome, such is the case with skin grafts, muscle flaps, skin flaps, or myocardial infarction to mention a few. Enhanced angiogenic properties of stem cells may pave the way for better outcomes and results for patients.
