Human Umbilical Cord Mesenchymal Stem Cells Ameliorate Cognitive Decline by Restoring Senescent Microglial Function via NF-κB-SREBP1 Pathway Inhibition.
Article in Aging cell, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Aging is a major risk factor for neurodegenerative diseases, yet the role of senescent microglia in age-related cognitive dysfunction remains incompletely understood. Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) have been extensively studied for their significant potential in anti-aging. In this study, we demonstrated that hUC-MSCs ameliorate age-related cognitive decline and downregulate senescence-associated markers in the aged hippocampus. Furthermore, co-culture experiments showed that senescent microglia exacerbate neuronal senescence and neuroinflammation, while also suppressing the apoptosis of senescent neurons. These findings suggested that senescent microglia contribute to age-related cognitive decline by exacerbating neuronal damage and impairing senescent neurons' clearance. We also elucidated a novel mechanism by which hUC-MSCs alleviate age-related cognitive decline by targeting senescent microglia. Specifically, we showed that hUC-MSCs reduce senescence-associated markers, decrease lipid droplet accumulation, and restore phagocytic function in senescent microglia through the inhibition of the NF-κB-SREBP1 pathway. This pathway modulation attenuates neuronal damage and promotes the apoptosis of senescent neurons, facilitating the clearance of damaged neurons. These findings highlight the therapeutic potential of hUC-MSCs in age-related neurodegenerative disorders.
