With the goal of studying skin wound healing and testing new drug treatments to enhance wound healing in rodent models, there is a clear need for improved splinting techniques to increase surgical efficiency and support routine wound monitoring. Splinted wound healing models humanize wound healing in rodents to prevent contraction and instead heal through granulation tissue deposition, increasing the relevance to human wound healing. Current technologies require suturing and heavy wrapping, leading to splint failure and cumbersome monitoring of the wound. In this study, we developed a splint with resealable cap system that provides ease of access for wound inspection, therapeutic treatment delivery, and routine wound imaging without the need to unwrap and wrap the animal. Meanwhile, to overcome the challenges associated with suturing, we also developed adherent splints that can be applied to both hairless or haired mice with minimal wrapping. Both technologies are expected to improve and encourage the adoption of splinted wound healing models.
为了研究皮肤伤口愈合并在啮齿动物模型中测试促进伤口愈合的新药物治疗方法,显然需要改进夹板技术以提高手术效率并支持常规伤口监测。夹板伤口愈合模型使啮齿动物的伤口愈合更接近人类情况,防止伤口收缩,而是通过肉芽组织沉积来愈合,从而增加了与人类伤口愈合的相关性。当前的技术需要缝合和大量包扎,导致夹板失效以及对伤口的监测繁琐。在本研究中,我们开发了一种带有可重新密封帽系统的夹板,该系统便于进行伤口检查、治疗给药以及常规伤口成像,而无需解开和重新包扎动物。同时,为了克服与缝合相关的挑战,我们还开发了粘贴式夹板,这种夹板只需最少的包扎就能应用于无毛或有毛小鼠。预计这两种技术都将改进并促进夹板伤口愈合模型的应用。
