Patient-derived induced pluripotent stem cells (iPSCs) enable the personalized study of RDEB pathogenesis and potential therapies. However, current skin cell differentiation protocols via 2D culture perform suboptimally when applied to engineered 3D skin constructs (ESC). Here, we present an approach to source fibroblasts (iFBs) and keratinocytes (iKCs) from iPSC-derived skin organoids using an optimized differentiation protocol, and utilize them to engineer ESCs modeling wild-type and RDEB phenotypes. The resulting iPSC-derived skin cells display marker expression consistent with primary counterparts and produce ESCs exhibiting significant extracellular matrix remodeling, protein deposition, and epidermal differentiation. RDEB constructs recapitulated hallmark disease features, including absence of collagen VII and reduced iFB proliferation. This work establishes a robust and scalable strategy for generating physiologically-relevant, iPSC-derived skin constructs, offering a powerful model for studying RDEB mechanisms and advancing personalized regenerative medicine.\n                  <\/jats:p>","DOI":"10.1177\/20417314251397594","type":"journal-article","created":{"date-parts":[[2025,12,1]],"date-time":"2025-12-01T09:15:27Z","timestamp":1764580527000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["IPSC-derived organoid-sourced skin cells enable functional 3D skin modeling of recessive dystrophic epidermolysis bullosa"],"prefix":"10.1177","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-4895-0497","authenticated-orcid":false,"given":"Laura","family":"Garriga-Cerda","sequence":"first","affiliation":[{"name":"Department of Dermatology, Columbia University Medical Center, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto","family":"Pappalardo","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Columbia University Medical Center, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charlotte Y.","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Columbia University, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey","family":"Kysar","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Columbia University, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5989-0242","authenticated-orcid":false,"given":"Kristin","family":"Myers","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Columbia University, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hasan Erbil","family":"Abaci","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Columbia University Medical Center, New York, NY, USA"},{"name":"Department of Biomedical Engineering, Columbia University, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,12]]},"reference":[{"key":"e_1_3_3_2_2","first-page":"45","article-title":"Management of chronic wounds in patients with dystrophic epidermolysis bullosa: challenges and solutions","volume":"4","author":"Rashidghamat E","year":"2017","unstructured":"Rashidghamat E, Melleri JE.
