Symptoms include swollen gingiva, tooth loss and, ultimately, ineffective mastication. Clinicians utilize regenerative techniques to rebuild and recover damaged periodontal tissues, especially in advanced periodontitis. Human periodontal ligament stem cells (hPDLSCs) are considered an appealing source of stem cells for regenerative therapy in periodontium. hPDLSCs manifest the main properties of mesenchymal stem cells, including the ability to self-renew and to differentiate in mesodermal cells. Significant progress has been made for clinical application of hPDLSCs; nevertheless, some problems remain, including the small number of cells isolated from each sample. In recent decades, hPDLSC ex vivo expansion and differentiation have been improved by modifying cell culture conditions, especially with the supplementation of cytokines\u2019 or growth factors\u2019 mix, chemicals, and natural compounds, or by using the decellularized extracellular matrix. Here, we analyzed the changes in stemness properties and differentiation potential of hPDLSCs when culturing in alternative media. In addition, we focused on the possibility of replacing FBS with human emoderivates to minimize the risks of xenoimmunization or zoonotic transmission when cells are expanded for therapeutic purposes.<\/jats:p>","DOI":"10.3390\/ijms24097798","type":"journal-article","created":{"date-parts":[[2023,4,25]],"date-time":"2023-04-25T02:06:35Z","timestamp":1682388395000},"page":"7798","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["A Review of Novel Strategies for Human Periodontal Ligament Stem Cell Ex Vivo Expansion: Are They an Evidence-Based Promise for Regenerative Periodontal Therapy?"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8294-8684","authenticated-orcid":false,"given":"Anna","family":"Di Vito","sequence":"first","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University Magna Gr\u00e6cia of Catanzaro, 88100 Catanzaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica","family":"Bria","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University Magna Gr\u00e6cia of Catanzaro, 88100 Catanzaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9557-3586","authenticated-orcid":false,"given":"Alessandro","family":"Antonelli","sequence":"additional","affiliation":[{"name":"Department of Health Science, University Magna Gr\u00e6cia of Catanzaro, 88100 Catanzaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5455-168X","authenticated-orcid":false,"given":"Maria","family":"Mesuraca","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University Magna Gr\u00e6cia of Catanzaro, 88100 Catanzaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9044-4929","authenticated-orcid":false,"given":"Tullio","family":"Barni","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University Magna Gr\u00e6cia of Catanzaro, 88100 Catanzaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9374-0566","authenticated-orcid":false,"given":"Amerigo","family":"Giudice","sequence":"additional","affiliation":[{"name":"Department of Health Science, University Magna Gr\u00e6cia of Catanzaro, 88100 Catanzaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8314-715X","authenticated-orcid":false,"given":"Emanuela","family":"Chiarella","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University Magna Gr\u00e6cia of Catanzaro, 88100 Catanzaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"462","DOI":"10.1111\/idj.12630","article-title":"Current Concepts in the Management of Periodontitis","volume":"71","author":"Kwon","year":"2021","journal-title":"Int.
