项目摘要

DESCRIPTION (provided by applicant): To date no biological treatment options specifically targeting the hypoxic nature of chronic wounds have been developed and marketed. While administration of individual angiogenic factors may stimulate some aspects of angiogenesis, the simultaneous expression of multiple factors is required to promote morphologically and functionally normal vessels. In this Phase II study, we propose to characterize a human keratinocyte cell line genetically-modified to coordinately express elevated levels of multiple therapeutic factors. Advances in ex vivo genetic engineering of a patented human keratinocyte cell line at Stratatech Corporation has made it uniquely positioned to complete this work. If successful, the proposed research will ultimately lead to the development and commercialization of improved treatments to promote the healing of chronic wounds and other severe skin defects.

描述（由申请人提供）：迄今为止，尚未开发和销售专门针对慢性伤口缺氧性质的生物治疗方案。虽然施用单个血管生成因子可能会刺激血管生成的某些方面，但需要多种因子的同时表达才能促进形态和功能正常的血管。在这项 II 期研究中，我们建议对经过基因改造的人类角质形成细胞系进行表征，以协调表达升高水平的多种治疗因子。 Stratatech Corporation 在获得专利的人类角质形成细胞系的离体基因工程方面取得的进展使其在完成这项工作方面处于独特的地位。如果成功，拟议的研究最终将导致改进治疗方法的开发和商业化，以促进慢性伤口和其他严重皮肤缺陷的愈合。
