Here, we describe different protocols for the cultivation of primary corneal cells that were isolated from porcine eyes. This primary cell culture can be used to test new therapeutic options for corneal diseases, such as dry eye disease, traumatic injuries, or corneal infections, and to study limbal epithelial stem cell (LESC) expansion. Two different isolation methods were performed: the outgrowth and the collagenase method. To perform the outgrowth protocol, small explants of the corneal limbus were generated and incubated in culture flasks in an incubator for 4\u20135 weeks. Regarding the collagenase method, to extract corneal cells, porcine corneas were removed, cut into small pieces, and incubated with collagenase. After incubation and centrifugation, the cells were seeded in 6- or 12-well plates and incubated in an incubator for 2\u20133 weeks. The differences between corneal cell cultivation with fetal bovine serum (FBS) and without it are also discussed. Therefore, the main advantages of the outgrowth method are that it requires fewer porcine eyes, and it takes less time to be performed compared to the collagenase method. On the other hand, with the collagenase method, mature cells are obtained earlier, at about 2 to 3 weeks.<\/jats:p>","DOI":"10.3390\/mps6030050","type":"journal-article","created":{"date-parts":[[2023,5,15]],"date-time":"2023-05-15T08:28:56Z","timestamp":1684139336000},"page":"50","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Two Methods for the Isolation and Cultivation of Porcine Primary Corneal Cells"],"prefix":"10.3390","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7253-937X","authenticated-orcid":false,"given":"Alice Rocha Teixeira","family":"Netto","sequence":"first","affiliation":[{"name":"Centre for Ophthalmology, Clinical Research University Eye Hospital T\u00fcbingen, Eberhard Karls Universit\u00e4t T\u00fcbingen, Elfriede-Aulhorn-Stra\u00dfe 7, D-72076 T\u00fcbingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc Dieter","family":"Hrusa","sequence":"additional","affiliation":[{"name":"Centre for Ophthalmology, Clinical Research University Eye Hospital T\u00fcbingen, Eberhard Karls Universit\u00e4t T\u00fcbingen, Elfriede-Aulhorn-Stra\u00dfe 7, D-72076 T\u00fcbingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karl-Ulrich","family":"Bartz-Schmidt","sequence":"additional","affiliation":[{"name":"Centre for Ophthalmology, Clinical Research University Eye Hospital T\u00fcbingen, Eberhard Karls Universit\u00e4t T\u00fcbingen, Elfriede-Aulhorn-Stra\u00dfe 7, D-72076 T\u00fcbingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2385-5517","authenticated-orcid":false,"given":"Sven","family":"Schnichels","sequence":"additional","affiliation":[{"name":"Centre for Ophthalmology, Clinical Research University Eye Hospital T\u00fcbingen, Eberhard Karls Universit\u00e4t T\u00fcbingen, Elfriede-Aulhorn-Stra\u00dfe 7, D-72076 T\u00fcbingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8697-2569","authenticated-orcid":false,"given":"Jos\u00e9","family":"Hurst","sequence":"additional","affiliation":[{"name":"Centre for Ophthalmology, Clinical Research University Eye Hospital T\u00fcbingen, Eberhard Karls Universit\u00e4t T\u00fcbingen, Elfriede-Aulhorn-Stra\u00dfe 7, D-72076 T\u00fcbingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"588","DOI":"10.1016\/j.jcrs.2010.12.037","article-title":"Anatomy and physiology of the cornea","volume":"37","author":"DelMonte","year":"2011","journal-title":"J.
