In a recent study, we developed a scaffold from poly (1,8-octanediolco-citrate) incorporated decellularized amnion membrane (DAM-POC). The DAM-POC scaffold was biocompatible and could enhance soft and hard tissue regeneration when applied to repair the cleft palate in rat. The efficacy of the DAM-POC scaffold in oral repair had led us to hypothesize that it could be employed extensively in the medical field as a wound dressing. This study aimed to investigate the feasibility and efficacy of the DAM-POC scaffold as a film dressing in accelerating wound healing when applied in multiple tissue injuries. Our results demonstrated that both the DAM and DAM-POC scaffolds were biocompatible and anti-adhesive without causing severe foreign body reactions when covering wounds in abdominal wall, back muscle, tibia bone, and liver. In addition, the DAM-POC scaffold was superior to the DAM scaffold in reducing inflammation, preventing fibrosis, and regenerating tissues. In conclusion, the DAM-POC scaffold might potentially be adopted as a film dressing in a wide range of therapeutic applications and healing situations to protect the damaged tissues from the external environment and prevent infections.","PeriodicalId":19596,"journal":{"name":"Organogenesis","volume":"16 4","pages":"126-136"},"PeriodicalIF":2.3,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15476278.2020.1844507","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10290639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this research was to develop a porous silk fibroin (SF)-coated poly(ethylene terephthalate) (PET) graft with a diameter < 6 mm. The graft was compared with a gelatin-coated PET graft because the latter PET graft with a diameter ~ 6 mm was widely used as a commercial vascular graft. Initially, porous SF was prepared using Glyc as the porogen [termed SF(Glyc)] and the PET grafts were prepared through the double-Raschel knitting method. Subsequently, the degradation of the SF coating was monitored using protease XIV in vitro and was compared with that observed in gelatin-coated PET grafts. Finally, these grafts were also implanted into rats for an in vivo comparison. In degradation experiments, after 7 days, the SF was clearly digested by protease XIV, but the gelatin on the graft was still remained at the outer surface. In implantation experiments in rats, the SF(Glyc)-coated PET graft was rapidly degraded in vivo and remodeling to self-tissues was promoted compared with the gelatin-coated PET graft. Thrombus formation and intimal hyperplasia were observed in the gelatin-coated PET graft; however, such side reactions were not observed in the SF(Glyc)-coated PET graft. Thus, the porous SF(Glyc)-coated PET graft with a small diameter < 6 mm may be useful as a commercial vascular graft.","PeriodicalId":19596,"journal":{"name":"Organogenesis","volume":"16 1","pages":"1 - 13"},"PeriodicalIF":2.3,"publicationDate":"2020-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15476278.2019.1686295","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44443539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
