Project Summary Abstract The long term objective of the proposed research is to learn what controls whether injuries heal with scarring/fibrosis versus full regeneration of lost structures. The human health burden of fibrosis and scarring is enormous and affects every tissue from heart (lost heart function after a myocardial infarction) to lung (idiopathic lung fibrosis). Enhancing regeneration could prevent for example the almost universal recurrence of chronic wounds in the exact location where they previously appeared. We use the Wound Induced Hair Neogenesis (WIHN) model system where in the center of excisional wounds in mice a variable amount of regeneration occurs and de novo hair follicles form in a recapitulation of embryogenesis. The goal of this grant is to understand the factors which control the frequency of regeneration. We will directly test the mechanism and the ability for candidate molecules which enhance regeneration in mice and in human subjects. The results of this grant promise to help define new treatments and diagnostics to enhance regeneration and wound healing.

项目摘要 拟议研究的长期目标是了解是什么控制着受伤是否愈合， 疤痕/纤维化与丢失结构的完全再生。纤维化和瘢痕形成的人类健康负担是 巨大的，影响到从心脏（心肌梗死后失去心脏功能）到肺的每一个组织 （特发性肺纤维化）。例如，加强再生可以防止几乎普遍发生的 在之前出现的位置发现了慢性伤口我们使用伤口诱导毛发 新生（WIHN）模型系统，其中在小鼠的切除伤口的中心， 在胚胎发生的重演中发生再生并重新形成毛囊。这项资助的目的是 是了解控制再生频率的因素。我们将直接测试机制 以及增强小鼠和人类受试者再生的候选分子的能力。结果 这笔赠款的承诺，以帮助确定新的治疗和诊断，以加强再生和伤口 治愈
