BACKGROUND: Wound healing is a complex process including hemostasis, inflammation, proliferation, and remodeling during which an orchestrated array of biological and molecular events occurs to promote skin regeneration. Abnormalities in each step of the wound healing process lead to reparative rather than regenerative responses, thereby driving the formation of cutaneous scar. Patients suffering from scars represent serious health problems such as contractures, functional and esthetic concerns as well as painful, thick, and itchy complications, which generally decrease the quality of life and impose high medical costs. Therefore, therapies reducing cutaneous scarring are necessary to improve patients' rehabilitation. SUMMARY: Current approaches to remove scars, including surgical and nonsurgical methods, are not efficient enough, which is in principle due to our limited knowledge about underlying mechanisms of pathological as well as the physiological wound healing process. Thus, therapeutic interventions focused on basic science including genetic and epigenetic knowledge are recently taken into consideration as promising approaches for scar management since they have the potential to provide targeted therapies and improve the conventional treatments as well as present opportunities for combination therapy. In this review, we highlight the recent advances in skin regenerative medicine through genetic and epigenetic approaches to achieve novel insights for the development of safe, efficient, and reproducible therapies and discuss promising approaches for scar management. KEY MESSAGE: Genetic and epigenetic regulatory switches are promising targets for scar management, provided the associated challenges are to be addressed.
背景:伤口愈合是一个复杂的过程,包括止血、炎症、增殖和重塑,在此过程中发生一系列协调的生物和分子事件,以促进皮肤再生。伤口愈合过程中每个步骤的异常都会导致修复而不是再生反应,从而导致皮肤瘢痕的形成。患有瘢痕的患者代表着严重的健康问题,如挛缩、功能和美观问题以及疼痛、肥厚和瘙痒等并发症,这些问题通常会降低生活质量并带来高昂的医疗费用。因此,减少皮肤瘢痕形成的治疗方法对于改善患者的康复是必要的。
摘要:目前去除瘢痕的方法,包括手术和非手术方法,都不够有效,这主要是由于我们对病理性和生理性伤口愈合过程的潜在机制了解有限。因此,最近将治疗干预重点放在包括遗传和表观遗传知识的基础科学上,被认为是瘢痕管理的有前途的方法,因为它们有可能提供靶向治疗,并改善传统治疗方法,以及为联合治疗提供机会。在这篇综述中,我们通过遗传和表观遗传方法强调了皮肤再生医学的最新进展,以获得关于开发安全、有效和可重复治疗方法的新见解,并讨论了瘢痕管理的有前途的方法。
关键信息:遗传和表观遗传调控开关是瘢痕管理的有前途的靶点,但要解决相关的挑战。
