1 · What the graph read from 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.

2 · The registry

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

backgroundSarcopenia is defined by the age-related loss of muscle mass and function, with an impaired regenerative capacity of satellite cells (SCs). Despite their recognized importance in muscle regeneration, human model-based studies on SCs in sarcopenia are still lacking, limiting our understanding of their role in age-related muscle loss. Here, we aimed to develop a sarcopenia model using human pluripotent stem cells (hPSCs)-derived skeletal muscle organoids (hSkMOs) and prevent the sarcopenia progression by testosterone treatment.

methodsThe 3D hSkMOs were generated from hPSC and exhibited structurally and functionally mature muscle fibres and spinal-derived neurons including motor neurons and interneurons. The proportion of muscle and the diameter of muscle fibres were assessed. To investigate the acute pro-inflammatory response and intrinsic regenerative capacity of hSkMOs, we induced sarcopenia-like conditions by TNF-α treatment for 2 days and analysed. To model aging-induced sarcopenia and investigate the preventive effect of testosterone, chronic TNF-α treatment was applied, followed by testosterone administration. Histological, biochemical, molecular and electrophysiological analyses were conducted in various experiments.

resultWe employed a stepwise differentiation protocol from 2D paraxial mesodermal induction to 3D myogenic specification, concluding with a maturation culture system. We observed that the majority of cells were T/BRA- and TBX6-positive (

conclusionsWe successfully developed a hSkMOs to demonstrate the structural maturity of the skeletal muscle and its functional interaction with spinal-derived interneurons and motor neurons. Furthermore, we demonstrated that our hSkMOs are useful for modelling aging-induced sarcopenia and providing a valuable platform for testing therapeutic interventions.
