Located between the teeth and the alveolar bone, mechanical stress activates the mechanomodulatory functions of PdLFs including regulating local inflammation and activating further bone-remodeling cells. Previous studies suggested growth differentiation factor 15 (GDF15) as an important pro-inflammatory regulator during the PdLF mechanoresponse. GDF15 exerts its effects through both intracrine signaling and receptor binding, possibly even in an autocrine manner. The extent to which PdLFs are susceptible to extracellular GDF15 has not yet been investigated. Thus, our study aims to examine the influence of GDF15 exposure on the cellular properties of PdLFs and their mechanoresponse, which seems particularly relevant regarding disease- and aging-associated elevated GDF15 serum levels. Therefore, in addition to investigating potential GDF15 receptors, we analyzed its impact on the proliferation, survival, senescence, and differentiation of human PdLFs, demonstrating a pro-osteogenic effect upon long-term stimulation. Furthermore, we observed altered force-related inflammation and impaired osteoclast differentiation. Overall, our data suggest a major impact of extracellular GDF15 on PdLF differentiation and their mechanoresponse.<\/jats:p>","DOI":"10.3390\/ijms241210011","type":"journal-article","created":{"date-parts":[[2023,6,12]],"date-time":"2023-06-12T01:28:21Z","timestamp":1686533301000},"page":"10011","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["GDF15 Promotes the Osteogenic Cell Fate of Periodontal Ligament Fibroblasts, thus Affecting Their Mechanobiological Response"],"prefix":"10.3390","volume":"24","author":[{"given":"Lukas","family":"L\u00f6sch","sequence":"first","affiliation":[{"name":"Department of Orthodontics, University Hospital Jena, Leutragraben 3, 07743 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albert","family":"Stemmler","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, University Hospital Jena, Leutragraben 3, 07743 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrian","family":"Fischer","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, University Hospital Jena, Leutragraben 3, 07743 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Steinmetz","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, University Hospital Jena, Leutragraben 3, 07743 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa","family":"Schuldt","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, University Hospital Jena, Leutragraben 3, 07743 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph-Ludwig","family":"Hennig","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, University Hospital Jena, Leutragraben 3, 07743 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9347-0172","authenticated-orcid":false,"given":"Judit","family":"Symmank","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, University Hospital Jena, Leutragraben 3, 07743 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Collin","family":"Jacobs","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, University Hospital Jena, Leutragraben 3, 07743 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,11]]},"reference":[{"key":"ref_1","first-page":"247","article-title":"Orthodontic treatment and the oral health-related quality of life of patients","volume":"9","author":"Navabi","year":"2012","journal-title":"J.
