Characterization of subcutaneous and visceral de-differentiated fat cells.

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
objectiveThe capacity of mature adipocytes to de-differentiate into fibroblast-like cells has been demonstrated in vitro and a few, rather specific in vivo conditions. A detailed comparison between de-differentiated fat (DFAT) cells and adipose stem and progenitor cells (ASPCs) from different adipose depots is yet to be conducted. Moreover, whether de-differentiation of mature adipocytes from classical subcutaneous and visceral depots occurs under physiological conditions remains unknown.
methodsHere, we used in vitro "ceiling culture", single cell/nucleus RNA sequencing, epigenetic anaysis and genetic lineage tracing to address these unknowns.
resultsWe show that in vitro-derived DFAT cells have lower adipogenic potential and distinct cellular composition compared to ASPCs. In addition, DFAT cells derived from adipocytes of inguinal origin have dramatically higher adipogenic potential than DFAT cells of the epididymal origin, due in part to enhanced NF-KB signaling in the former. We also show that high-fat diet (HFD) feeding enhances DFAT cell colony formation and re-differentiation into adipocytes, while switching from HFD to chow diet (CD) only reverses their re-differentiation. Moreover, HFD deposits epigenetic changes in DFAT cells and ASPCs that are not reversed after returning to CD. Finally, combining genetic lineage tracing and single cell/nucleus RNA sequencing, we demonstrate the existence of DFAT cells in inguinal and epididymal adipose depots in vivo, with transcriptomes resembling late-stage ASPCs.
conclusionsThese data uncover the cell type- and depot-specific properties of DFAT cells, as well as their plasticity in response to dietary intervention. This knowledge may shed light on their role in life style change-induced weight loss and regain.
