However, their inferior mechanical properties, slow cross-linking, weak strengths, and poor supporting properties remain their inevitable challenges. In our study, we fabricated a novel dECM hydrogel with better crosslinking strength and speed, stronger support properties, and better mechanical properties. The hydrogel, which we named gelatin-based dECM powder hydrogel (gelatin-dECM hydrogel), was prepared by mixing dECM microparticles in gelatin solution and adding certain amount of 1-Ethyl-3-(3-dimethyl-aminopropyl-1-carbodiimide) (EDC) and N-hydroxysuccinimide (NHS). We evaluated the utility of this hydrogel by assessing the degradation rate, mechanical properties, and biocompatibility. The results showed that the gelatin-dECM hydrogel has high mechanical properties and biocompatibility and also has the ability to promote cell proliferation and migration. After injection of this hydrogel around the surgical sites of urethras in rabbits, the incorporation of dECM powder was demonstrated to promote angiogenesis as well as scarless repair by histological sections after surgery. The application of this novel hydrogel provides a new perspective for the treatment of post-traumatic urethral stricture.<\/jats:p>","DOI":"10.3390\/gels9110913","type":"journal-article","created":{"date-parts":[[2023,11,17]],"date-time":"2023-11-17T09:23:43Z","timestamp":1700213023000},"page":"913","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Injectable Decellularized Extracellular Matrix-Based Bio-Ink with Excellent Biocompatibility for Scarless Urethra Repair"],"prefix":"10.3390","volume":"9","author":[{"given":"Wenzhuo","family":"Fang","sequence":"first","affiliation":[{"name":"Department of Urology, Affiliated Sixth People\u2019s Hospital, Shanghai Jiaotong University, No. 600 Yi-Shan Road, Shanghai 200233, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Urology, Affiliated Sixth People\u2019s Hospital, Shanghai Jiaotong University, No. 600 Yi-Shan Road, Shanghai 200233, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yangwang","family":"Jin","sequence":"additional","affiliation":[{"name":"Department of Urology, Affiliated Sixth People\u2019s Hospital, Shanghai Jiaotong University, No. 600 Yi-Shan Road, Shanghai 200233, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaile","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Urology, Affiliated Sixth People\u2019s Hospital, Shanghai Jiaotong University, No. 600 Yi-Shan Road, Shanghai 200233, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Urology, Affiliated Sixth People\u2019s Hospital, Shanghai Jiaotong University, No. 600 Yi-Shan Road, Shanghai 200233, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meng","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Urology, Affiliated Sixth People\u2019s Hospital, Shanghai Jiaotong University, No. 600 Yi-Shan Road, Shanghai 200233, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuhui","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Urology, Affiliated Sixth People\u2019s Hospital, Shanghai Jiaotong University, No. 600 Yi-Shan Road, Shanghai 200233, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ranxing","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Urology, Affiliated Sixth People\u2019s Hospital, Shanghai Jiaotong University, No. 600 Yi-Shan Road, Shanghai 200233, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiang","family":"Fu","sequence":"additional","affiliation":[{"name":"Department of Urology, Affiliated Sixth People\u2019s Hospital, Shanghai Jiaotong University, No. 600 Yi-Shan Road, Shanghai 200233, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1009259","DOI":"10.3389\/fped.2023.1009259","article-title":"The surgical techniques of transperineal anastomotic urethroplasty for complex posterior urethral stenosis in boys and the long\u2013term follow up outcomes","volume":"11","author":"Zhu","year":"2023","journal-title":"Front.
