A Novel function of Nebivolol: Stimulation of Adipose-derived Stem Cell Proliferation and Inhibition of Differentiation.
Article in Journal of stem cells & regenerative medicine, 2020. 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
Tissue engineering is limited by the time of culture expansion of cells needed for scaffold seeding. Thus, a simple means of accelerated stem cell proliferation could represent a significant advance. Here, Nebivolol was investigated for its effect on the replicative capacity of adipose-derived stem cells (ASCs). This study indicates that the number of ASCs with Nebivolol treatment showed a significant population increase of 51.5% compared to untreated cells (p<0.01). Cell cycle analysis showed a significant decrease in the percentage of ASCs in G1 phase with Nebivolol treatment compared to untreated cells (p<0.01), suggesting that Nebivolol shortens the G1 phase of ASCs, resulting in a faster proliferative rate. Furthermore, our results showed that Nebivolol significantly increased colony-forming units of ASCs (p<0.01). Despite increasing ASC proliferative potential, we showed that Nebivolol has an inhibitory effect on adipogenic and osteogenic differentiation potential as indicated by significantly reduced expression of CCAAT Enhancer Binding Protein alpha (P<0.01) and lipoprotein lipase (P<0.01) and inhibited activity of alkaline phosphatase (P<0.01), respectively. Taken together, these results showed that Nebivolol accelerated ASC proliferation through shortening G1 phase, while inhibiting both adipogenic and osteogenic potentials of ASCs. These data identify a novel and simple approach to accelerate stem cell expansion
