Embryotrophic effect of exogenous protein contained adipose-derived stem cell extracellular vesicles.
Article in Journal of animal science and biotechnology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundExtracellular vesicles (EVs) regulate cell metabolism and various biological processes by delivering specific proteins and nucleic acids to surrounding cells. We aimed to investigate the effects of the cargo contained in EVs derived from adipose-derived stem cells (ASCs) on the porcine embryonic development.
methodsASCs were isolated from porcine adipose tissue and characterized using ASC-specific markers via flow cytometry. EVs were subsequently extracted from the conditioned media of the established ASCs. These EVs were added to the in vitro culture environment of porcine embryos to observe qualitative improvements in embryonic development. Furthermore, the proteins within the EVs were analyzed to investigate the underlying mechanisms.
resultsWe observed a higher blastocyst development rate and increased mitochondrial activity in early stage embryos in the ASC-EVs-supplemented group than in the controls (24.8% ± 0.8% vs. 28.6% ± 1.1%, respectively). The terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay of blastocysts also revealed significantly reduced apoptotic cells in the ASC-EVs-supplemented group. Furthermore, through proteomics, we detected the proteins in ASC-EVs and blastocysts from each treatment group. This analysis revealed a higher fraction of proteins in the ASC-EVs-supplemented group than in the controls (1,547 vs. 1,495, respectively). Gene analysis confirmed that ASC-EVs showed a high expression of tyrosine-protein kinase (SRC), whereas ASC-EVs supplemented blastocysts showed a higher expression of Cyclin-dependent kinase 1 (CDK1). SRC is postulated to activate protein kinase B (AKT), which inhibits the forkhead box O signaling pathway and activates CDK1. Subsequently, CDK1 activation influences the cell cycle, thereby affecting in vitro embryonic development.
conclusionASC-EVs promote mitochondrial activity, which is crucial for the early development of blastocysts and vital in the downregulation of apoptosis. Additionally, ASC-EVs supply SRC to porcine blastocysts, thereby elongating the cell cycle.
