Rejuvenation of the reconstitution potential and reversal of myeloid bias of aged HSCs upon pH treatment.
Article in Aging cell, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Aged hematopoietic stem cells (HSCs) show reduced reconstitution potential, limiting their use in transplantation settings in the clinic. We demonstrate here that exposure of aged HSCs ex vivo to a pH of 6.9 instead of the commonly used pH of 7.4 results in enhanced HSCs potential that is consistent with rejuvenation, including attenuation of the myeloid bias of aged HSC and restoration of a youthful frequency of epigenetic polarity. Rejuvenation of aged HSCs by pH 6.9 is, at least in part, due to alterations in the polyamine/methionine pathway within pH 6.9 HSCs, and consequently, attenuation of the production of spermidine also attenuated aging of HSCs. Exposure of aged HSCs to pH 6.9, or pharmacological targeting of the polyamine pathway, might thus extend the use of HSCs from aged donors for therapeutic applications.
