Technical note: an optimized method to isolate, purify, and differentiate satellite cells from broiler chicks.

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
Development and maintenance of healthy muscle fibers rely on the myogenic potential of satellite cells (SC), muscle stem cells that proliferate and differentiate to form myotubes. Satellite cells are indispensable for post-hatch muscle growth as well as muscle repair and regeneration when myofibers are damaged. Pectoralis major of young broiler chicks (5-d olds) is a readily available source of SC, which can be used in vitro to elucidate cellular and molecular mechanisms responsible for muscle growth and regeneration in broilers. Here, we optimized a method for efficient isolation, purification, and differentiation of SC, from young broiler chicks. This procedure includes a simple method that allows SC to be purified from other muscle cell types that can impede the fidelity of follow-on experiments, particularly highly sensitive measures such as RNAseq. The methods for culturing and differentiating SC into multinucleated myotubes were also optimized by testing serum types, concentrations, and the effects of chicken embryo extract. Using the isolation procedure, a highly pure SC population (94.6 ± 2.11% Pax7+) with high viability and yield was obtained, and their capacity to differentiate into myotubes was confirmed. Enrichment for SC and myogenic capacity were maintained through multiple passages and after cryopreservation. Analysis of gene expression over the first 48 h of differentiation confirmed that SC exhibited the expected molecular signature of myogenesis. Taken together, this method simplifies the ability to isolate and maintain a relatively pure population of SC with strong myogenic potential from young broiler chicks, and should support downstream applications for assessing the impact of nutrients, metabolites, and other physiological cues on muscle growth and development in broilers.
