However, the molecular mechanisms involved in sensing mechanical stress during muscle formation remain unclear. Here, we investigated the role of the mechanosensitive ion channel Piezo1 during myogenic progression of both fast and slow muscle satellite cells. We found that Piezo1 level increases during myogenic differentiation and direct manipulation of Piezo1 in muscle stem cells alters the myogenic progression. Indeed, Piezo1 knockdown suppresses myoblast fusion, leading to smaller myotubes. Such an event is accompanied by significant downregulation of the fusogenic protein Myomaker. In parallel, while Piezo1 knockdown also lowers Ca2+ influx in response to stretch, Piezo1 activation increases Ca2+ influx in response to stretch and enhances myoblasts fusion. These findings may help understand molecular defects present in some muscle diseases. Our study shows that Piezo1 is essential for terminal muscle differentiation acting on myoblast fusion, suggesting that Piezo1 deregulation may have implications in muscle aging and degenerative diseases, including muscular dystrophies and neuromuscular disorders.<\/jats:p>","DOI":"10.3390\/cells11030393","type":"journal-article","created":{"date-parts":[[2022,1,25]],"date-time":"2022-01-25T20:44:33Z","timestamp":1643143473000},"page":"393","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["Fine-Tuning of Piezo1 Expression and Activity Ensures Efficient Myoblast Fusion during Skeletal Myogenesis"],"prefix":"10.3390","volume":"11","author":[{"given":"Huascar Pedro","family":"Ortuste Quiroga","sequence":"first","affiliation":[{"name":"Department of Physiology, Graduate School of Health Sciences, Toyohashi SOZO University, Aichi, Toyohashi 440-0016, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Massimo","family":"Ganassi","sequence":"additional","affiliation":[{"name":"Randall Centre for Cell and Molecular Biophysics, King\u2019s College London, London SE1 1UL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shingo","family":"Yokoyama","sequence":"additional","affiliation":[{"name":"Laboratory of Physiology, School of Health Sciences, Toyohashi SOZO University, Aichi, Toyohashi 440-0016, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kodai","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Department of Physiology, Graduate School of Health Sciences, Toyohashi SOZO University, Aichi, Toyohashi 440-0016, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomohiro","family":"Yamashita","sequence":"additional","affiliation":[{"name":"Department of Physiology, Graduate School of Health Sciences, Toyohashi SOZO University, Aichi, Toyohashi 440-0016, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Raimbach","sequence":"additional","affiliation":[{"name":"Centre of Human and Aerospace Physiological Sciences, King\u2019s College London, London SE1 1UL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arisa","family":"Hagiwara","sequence":"additional","affiliation":[{"name":"Department of Physiology, Graduate School of Health Sciences, Toyohashi SOZO University, Aichi, Toyohashi 440-0016, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oscar","family":"Harrington","sequence":"additional","affiliation":[{"name":"Centre of Human and Aerospace Physiological Sciences, King\u2019s College London, London SE1 1UL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jodie","family":"Breach-Teji","sequence":"additional","affiliation":[{"name":"Centre of Human and Aerospace Physiological Sciences, King\u2019s College London, London SE1 1UL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsushi","family":"Asakura","sequence":"additional","affiliation":[{"name":"Paul & Sheila Wellstone Muscular Dystrophy Center, Department of Neurology, Stem Cell Institute, University of Minnesota Medical School, Minneapolis, MN 55455, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0010-1867","authenticated-orcid":false,"given":"Yoshiro","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Division of Cell Signalling, National Institute for Physiological Sciences, Aichi, Okazaki 444-0864, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makoto","family":"Tominaga","sequence":"additional","affiliation":[{"name":"Division of Cell Signalling, National Institute for Physiological Sciences, Aichi, Okazaki 444-0864, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter S.","family":"Zammit","sequence":"additional","affiliation":[{"name":"Randall Centre for Cell and Molecular Biophysics, King\u2019s College London, London SE1 1UL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5380-4561","authenticated-orcid":false,"given":"Katsumasa","family":"Goto","sequence":"additional","affiliation":[{"name":"Department of Physiology, Graduate School of Health Sciences, Toyohashi SOZO University, Aichi, Toyohashi 440-0016, Japan"},{"name":"Laboratory of Physiology, School of Health Sciences, Toyohashi SOZO University, Aichi, Toyohashi 440-0016, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"493","DOI":"10.1083\/jcb.9.2.493","article-title":"Satellite Cell of Skeletal Muscle Fibers","volume":"9","author":"Mauro","year":"1961","journal-title":"J.
