A mechanical testing protocol is developed to investigate the large-strain response of ex vivo cervical tissue samples in uniaxial tension in its two principal anatomical locations, the epithelial and connective layers. The final aim of this work is to compare the reconstructed shear modulus of the epithelial and connective layers of cervical tissue. According to the obtained results, the nonlinear parameter A from the proposed FOEC model could be an important biomarker in cervical tissue diagnosis. In addition, the calculated shear modulus depended on the anatomical location of the cervical tissue (\u03bcepithelial = 1.29 \u00b1 0.15 MPa, and \u03bcconnective = 3.60 \u00b1 0.63 MPa).<\/jats:p>","DOI":"10.3390\/s20164362","type":"journal-article","created":{"date-parts":[[2020,8,5]],"date-time":"2020-08-05T15:13:18Z","timestamp":1596640398000},"page":"4362","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Hyperelastic Ex Vivo Cervical Tissue Mechanical Characterization"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3196-5935","authenticated-orcid":false,"given":"Antonio","family":"Callejas","sequence":"first","affiliation":[{"name":"Department of Structural Mechanics, University of Granada, 18010 Granada, Spain"},{"name":"Instituto de Investigaci\u00f3n Biosanitaria, ibs.GRANADA, 18012 Granada, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5542-1588","authenticated-orcid":false,"given":"Juan","family":"Melchor","sequence":"additional","affiliation":[{"name":"Instituto de Investigaci\u00f3n Biosanitaria, ibs.GRANADA, 18012 Granada, Spain"},{"name":"Excellence Research Unit, \u201cModelling Nature\u201d (MNat), University of Granada, 18010 Granada, Spain"},{"name":"Department of Statistics and Operations Research, University of Granada, 18010 Granada, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9026-3784","authenticated-orcid":false,"given":"Inas H.","family":"Faris","sequence":"additional","affiliation":[{"name":"Department of Structural Mechanics, University of Granada, 18010 Granada, Spain"},{"name":"Instituto de Investigaci\u00f3n Biosanitaria, ibs.GRANADA, 18012 Granada, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9239-294X","authenticated-orcid":false,"given":"Guillermo","family":"Rus","sequence":"additional","affiliation":[{"name":"Department of Structural Mechanics, University of Granada, 18010 Granada, Spain"},{"name":"Instituto de Investigaci\u00f3n Biosanitaria, ibs.GRANADA, 18012 Granada, Spain"},{"name":"Excellence Research Unit, \u201cModelling Nature\u201d (MNat), University of Granada, 18010 Granada, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"160rv12","DOI":"10.1126\/scitranslmed.3004890","article-title":"Engineering complex tissues","volume":"4","author":"Atala","year":"2012","journal-title":"Sci.
