Here, we introduce a self-assembled interleukin-4 (IL-4) peptide hydrogel designed to shift MSC populations toward a homogeneous CD106\n                    <jats:sup>+<\/jats:sup>\n                    subset with enhanced regenerative and immunomodulatory capabilities. To evaluate their therapeutic potential, MSCs with the IL-4 hydrogel were administered to a murine model of acute kidney injury (AKI) via renal capsule transplantation. Compared with untreated MSCs, encapsulated MSCs exhibited superior engraftment and survival, leading to significant improvements in renal function, as evidenced by reduced serum creatinine levels, attenuated tubular necrosis, and decreased inflammatory infiltrates. These findings highlight the IL-4 peptide hydrogel as a promising platform for overcoming MSC heterogeneity and manufacturing disease-specific MSCs, offering a scalable strategy for advanced cell therapies in AKI and beyond.\n                  <\/jats:p>","DOI":"10.1073\/pnas.2536368123","type":"journal-article","created":{"date-parts":[[2026,6,10]],"date-time":"2026-06-10T17:38:23Z","timestamp":1781113103000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":1,"title":["IL-4 peptide hydrogel reprograms MSC heterogeneity toward the CD106+ population for enhanced renal repair"],"prefix":"10.1073","volume":"123","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-2871-6969","authenticated-orcid":false,"given":"Kai","family":"Pan","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/047hegk60","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Cardiology, Zhengzhou Seventh People\u2019s Hospital","place":["Zhengzhou, China"]},{"id":[{"id":"https:\/\/ror.org\/01y1kjr75","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Pathophysiology, School of Medicine, Nankai University","place":["Tianjin, China"]},{"id":[{"id":"https:\/\/ror.org\/038hzq450","id-type":"ROR","asserted-by":"publisher"}],"name":"Henan Key Laboratory of Medical Tissue Regeneration, Department of Anatomy, Henan Medical University","place":["Xinxiang 453003, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enze","family":"Fu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01y1kjr75","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Pathophysiology, School of Medicine, Nankai University","place":["Tianjin, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-6326-9760","authenticated-orcid":false,"given":"Wenlong","family":"Wang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/021cj6z65","id-type":"ROR","asserted-by":"publisher"}],"name":"Qingdao Medical College, Qingdao University","place":["Qingdao, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-5126-2736","authenticated-orcid":false,"given":"Rui","family":"Li","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01y1kjr75","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Pathophysiology, School of Medicine, Nankai University","place":["Tianjin, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiansheng","family":"Yang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01y1kjr75","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Pathophysiology, School of Medicine, Nankai University","place":["Tianjin, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1639-9074","authenticated-orcid":false,"given":"Hongyan","family":"Tao","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01y1kjr75","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Pathophysiology, School of Medicine, Nankai University","place":["Tianjin, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhibo","family":"Han","sequence":"additional","affiliation":[{"name":"Tianjin Key Laboratory of Engineering Technologies for Cell Pharmaceutical, National Engineering Research Center of Cell Products, AmCellGene Co.
