To address these challenges, a sericin hydrogel exhibiting outstanding physical and chemical properties along with cytocompatibility was prepared through crosslinking genipin with degraded sericin extracted from fibroin deficient silkworm cocoons by the high temperature and pressure method. Our reported sericin hydrogels possess good elasticity, injectability, and robust behaviors. The 8% sericin hydrogel can smoothly pass through a 16 G needle. While the 12% sericin hydrogel remains intact until its compression ratio reaches 70%, accompanied by a compression strength of 674 kPa. 12% sericin hydrogel produce a maximum stretch of 740%, with breaking strength and tensile modulus of 375 kPa and 477 kPa respectively. Besides that, the hydrogel system demonstrated remarkable cell-adhesive capabilities, effectively promoting cell attachment and, proliferation. Moreover, the swelling and degradation behaviors of the hydrogels are pH responsiveness. Sericin hydrogel releases drugs in a sustained manner. Furthermore, this study addresses the challenge of sterilizing sericin hydrogels (sterilization will inevitably lead to the destruction of their structures). In addition, it challenges the prior notion that sericin extracted under high temperature and pressure is difficult to directly cross-linked into a stable hydrogel. This developed hydrogel system in this study holds promise to be a new multifunctional platform expanding the application area scope of sericin.<\/jats:p>","DOI":"10.3390\/gels9120948","type":"journal-article","created":{"date-parts":[[2023,12,3]],"date-time":"2023-12-03T04:59:16Z","timestamp":1701579556000},"page":"948","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["A Sterile, Injectable, and Robust Sericin Hydrogel Prepared by Degraded Sericin"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8166-8448","authenticated-orcid":false,"given":"Yeshun","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Biotechnology, Jiangsu University of Science and Technology, Zhenjiang 212100, China"},{"name":"Key Laboratory of Silkworm and Mulberry Genetic Improvement, Ministry of Agriculture and Rural Affairs, Sericultural Research Institute, Chinese Academy of Agricultural Sciences, Zhenjiang 212100, China"},{"name":"Zhenjiang Zhongnong Biotechnology Co., Ltd., Zhenjiang 212121, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susu","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Jiangsu University of Science and Technology, Zhenjiang 212100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yurong","family":"Li","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Jiangsu University of Science and Technology, Zhenjiang 212100, China"},{"name":"Key Laboratory of Silkworm and Mulberry Genetic Improvement, Ministry of Agriculture and Rural Affairs, Sericultural Research Institute, Chinese Academy of Agricultural Sciences, Zhenjiang 212100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang","family":"Li","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Jiangsu University of Science and Technology, Zhenjiang 212100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhanyan","family":"Du","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Jiangsu University of Science and Technology, Zhenjiang 212100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siyu","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Jiangsu University of Science and Technology, Zhenjiang 212100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yushuo","family":"Song","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Jiangsu University of Science and Technology, Zhenjiang 212100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanyan","family":"Li","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Jiangsu University of Science and Technology, Zhenjiang 212100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guozheng","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Biotechnology, Jiangsu University of Science and Technology, Zhenjiang 212100, China"},{"name":"Key Laboratory of Silkworm and Mulberry Genetic Improvement, Ministry of Agriculture and Rural Affairs, Sericultural Research Institute, Chinese Academy of Agricultural Sciences, Zhenjiang 212100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Liu, J., Shi, L., Deng, Y., Zou, M.Z., Cai, B., Song, Y., Wang, Z., and Wang, L.
