Angiogenic properties and intercellular communication of differentiated porcine endothelial cells in vascular therapy.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Endothelial cell dysfunction can lead to various vascular diseases. Blood flow disorder is a common symptom of vascular diseases. Regenerative angiogenesis, which involves transplanting vascular cells or stem cells into the body to shape new vasculature, can be a good therapeutic strategy. However, there are several limitations to using autologous cells from the patients themselves. We sought to investigate the new vascular cells that can play a role in the formation of angiogenesis in vivo using stem cells from alternative animals suitable for cellular therapy. Porcine is an optimal animal model for xenotransplantation owing to its physiological similarity to humans. We used differentiated porcine endothelial cells (pECs) as a therapeutic strategy to restore vessel function. Differentiated pECs formed vessel-like structures in mice, distinguishing them from stem cells. MMPs activity and migration assays indicated that differentiated pECs possessed angiogenic potential. Tube formation and 3D spheroid sprouting assays further confirmed the angiogenic phenotype of the differentiated pECs. Immunofluorescence and immunoprecipitation analyses revealed claudin-mediated tight junctions and connexin 43-mediated gap junctions between human ECs and differentiated pECs. Additionally, the movement of small RNA from human ECs to differentiated pECs was observed under co-culture conditions. Our findings demonstrated the in vivo viability and angiogenetic potential of differentiated pECs and highlighted the potential for intercellular communication between human and porcine ECs. These results suggest that transplanted cells in vascular regeneration completed after cell therapy have the potential to achieve intercellular communication within the body.
