Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The hindlimb unloaded (HU) mouse model exhibits disuse-induced muscle atrophy. However, effective interventions remain elusive. We investigated the therapeutic potential of mesenchymal stem cells (MSC) transplant on muscle decline in HU mice. We divided 4-month-old male c57BL/6j mice into controls and HU mice treated with PBS as placebo (HU-PBS) or MSCs (HU-MSC; one million cells/100 μl PBS into gastrocnemius muscles once a week) for three weeks. We measured muscle mass, grip strength, and an unbiased transcriptome analysis of gastrocnemius muscles. MSC treatment prevented muscle atrophy and improved grip strength in HU mice. Transcriptome analysis revealed MSC-induced unique (557 genes) and differential (1214 genes) expressions of several genes compared to the HU-PBS group. GO and KEGG term analysis revealed an HU-induced downregulation of pathways associated with the regulation of contractile apparatus, neuromuscular junction, and satellite cell function, which were partly reversed with MSC treatment. Lastly, MSC treatment also upregulated the pathways controlling muscle differentiation and growth in the HU mice. Altogether, we report the therapeutic potential of MSCs in treating disuse-induced muscle atrophy and weakness. Our study may help unravel novel molecular mechanisms involved in MSCs-induced muscle restoration.
