This study aimed to present a co-culture method that promotes the differentiation of retinal progenitor cells (RPCs) in the presence of retinal pigment epithelium (RPE) cells.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We implemented a three-dimensional culture system using a modified alginate substrate to culture human embryonic stem cell-derived RPCs on top of an RPE layer, mimicking an in vivo environment. The characteristics of RPCs in experimental and control groups were analyzed at the RNA and protein levels, and the 3D retinal-like structures were examined by H&amp;E staining. Statistical analysis was conducted in GraphPad Prism (v5.1) using unpaired Student\u2019s t-tests and one-way ANOVA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Hypoxic culture conditions better maintained na\u00efve RPC characteristics than normoxic conditions, with significantly higher expression of RAX, LHX2, and PAX6. The addition of Matrigel to simulate the subretinal space supported RPE survival. In this 3D coculture model, RPCs differentiated into neural tube\u2013like structures\u2014potentially due to RPE-secreted inductive factors\u2014and exhibited higher expression of photoreceptor markers than RPCs cultured without RPE.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Our results demonstrate that a 3D coculture system can be used to investigate the cellular and molecular mechanisms underlying retinal development and to support the formation of 3D retinal structures for future preclinical and clinical applications.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/08853282251414276","type":"journal-article","created":{"date-parts":[[2026,1,8]],"date-time":"2026-01-08T20:36:47Z","timestamp":1767904607000},"page":"273-284","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Generation of a three-dimensional retinal-like structure using a laminin-111-modified alginate layer"],"prefix":"10.1177","volume":"41","author":[{"given":"Samaneh","family":"Najafian","sequence":"first","affiliation":[{"name":"ACECR Institute of Higher Education (Isfahan Branch)"},{"name":"Cell Science Research Center, Royan Institute for Biotechnology, ACECR"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1983-3435","authenticated-orcid":false,"given":"Mohammad Hossein","family":"Nasr Esfahani","sequence":"additional","affiliation":[{"name":"Cell Science Research Center, Royan Institute for Biotechnology, ACECR"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amirreza","family":"Haghighatnejad","sequence":"additional","affiliation":[{"name":"Islamic Azad University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2413-4890","authenticated-orcid":false,"given":"Fereshteh","family":"Karamali","sequence":"additional","affiliation":[{"name":"Cell Science Research Center, Royan Institute for Biotechnology, ACECR"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,1,8]]},"reference":[{"key":"e_1_3_5_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1442-9071.2010.02363.x"},{"key":"e_1_3_5_3_2","doi-asserted-by":"publisher","DOI":"10.1289\/ehp.82441"},{"key":"e_1_3_5_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.celrep.2017.03.040"},{"key":"e_1_3_5_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/jnr.21813"},{"key":"e_1_3_5_6_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.20-19-07149.2000"},{"key":"e_1_3_5_7_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0023148"},{"key":"e_1_3_5_8_2","doi-asserted-by":"publisher","DOI":"10.1089\/hum.2011.060"},{"key":"e_1_3_5_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(12)60028-2"},{"key":"e_1_3_5_10_2","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.15-18681"},{"key":"e_1_3_5_11_2","doi-asserted-by":"publisher","DOI":"10.1038\/nbt.4114"},{"key":"e_1_3_5_12_2","doi-asserted-by":"publisher","DOI":"10.1126\/scitranslmed.aao4097"},{"key":"e_1_3_5_13_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1608368"},{"key":"e_1_3_5_14_2","first-page":"1","article-title":"Therapy.
