Adipose Tissue-Derived Mesenchymal Stem Cells Alter Metabolites of Brain Cholesterol Homeostasis in An Alzheimer's Model.
Article in Cell journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveDisruption of cholesterol homeostasis in Alzheimer's disease (AD) plays a crucial role in disease pathogenesis, making it a potential therapeutic target. Mesenchymal stem cells (MSCs) show promise in treating cognitive impairment and provide a novel therapeutic approach. This study aims to investigate the effects of MSCs on specific metabolites associated with brain cholesterol homeostasis in an AD rat model. MATERIALS AND
methodsIn this experimental study, animals were divided into three groups: control, AD, and AD+MSCs. AD was induced using amyloid beta (Aβ) and confirmed through the Morris water maze (MWM) behavioural test and Congo red staining. MSCs were extracted, characterised via flow cytometry, subjected to osteoblast and adipose differentiation, and injected intraventricularly. The cholesterol metabolite levels were measured using gas chromatography-mass spectrometry (GC)-MS and compared among the groups.
resultsTreatment with MSCs significantly improved memory function in the AD+MSCs group compared to the AD group and the number of beta-amyloid plaques decreased according to histological assessment. Disturbances in the brain cholesterol metabolites that included desmosterol, 7-dehydrocholesterol, 24S-hydroxycholesterol, 27-hydroxycholesterol and cholesterol were observed in the AD group compared to the control group. Treatment with MSCs resulted in significant alterations in the levels of these metabolites.
conclusionThe findings indicate that MSC therapy has the potential to improve AD by modulating brain cholesterol homeostasis and promoting the differentiation of stem cells into nerve cells. The results emphasize the importance of investigating the role of cholesterol metabolites in the context of MSC therapy to gain deeper insights into underlying mechanisms of the therapeutic efficacy of MSCs in AD.
