Effects of human amniotic membrane on the angiogenesis and healing of ischemic wounds in a rat model.
Although the human amniotic membrane (hAM) has been demonstrated to promote angiogenesis, its efficacy in healing ischemic wounds remains unknown. Therefore, the current study aimed to evaluate the potential of hAM as a dressing for treating ischemic wounds. The inferior abdominal wall arteries and veins of male rats were divided, and an ischemic wound was created on each side of the abdominal wall. Of the two ischemic wounds created, only one was covered with hAM, and its wound healing effect was determined by measuring the wound area. Angiogenesis was assessed by measuring microvessel density (MVD). On day 5, the mean wound area changed from 400 mm2 to 335.4 (260-450) mm2 in the hAM group and to 459 (306-570) mm2 in the control group (p = 0.0051). MVD was 19.0 (10.4-24.6) in the hAM group and 15.1 (10.6-20.8) in the control group (p = 0.0026). No significant differences in local pro- and anti-inflammatory cytokine levels were observed between the two groups. Histological examination revealed no rejection of the transplanted hAM. Therefore, the hAM may serve as a novel wound dressing that can promote angiogenesis and healing in ischemic wounds.
期刊介绍：
The Journal of Biomaterials Applications is a fully peer reviewed international journal that publishes original research and review articles that emphasize the development, manufacture and clinical applications of biomaterials.
Peer-reviewed articles by biomedical specialists from around the world cover:
New developments in biomaterials, R&D, properties and performance, evaluation and applications
Applications in biomedical materials and devices - from sutures and wound dressings to biosensors and cardiovascular devices
Current findings in biological compatibility/incompatibility of biomaterials
The Journal of Biomaterials Applications publishes original articles that emphasize the development, manufacture and clinical applications of biomaterials. Biomaterials continue to be one of the most rapidly growing areas of research in plastics today and certainly one of the biggest technical challenges, since biomaterial performance is dependent on polymer compatibility with the aggressive biological environment. The Journal cuts across disciplines and focuses on medical research and topics that present the broadest view of practical applications of biomaterials in actual clinical use.
The Journal of Biomaterial Applications is devoted to new and emerging biomaterials technologies, particularly focusing on the many applications which are under development at industrial biomedical and polymer research facilities, as well as the ongoing activities in academic, medical and applied clinical uses of devices.
