Micro-patterned polymer substrates as novel models of epidermal wound healing

点击翻译按钮获取中文摘要

The proposed research will develop a novel in vitro model of wound healing within the skin. We will employ state-of-the-art micro-fabrication techniques to create engineered substrates for culturing human keratinocytes. This technology will allow us to precisely control multiple parameters of the wound environment. Specifically, we will determine how the composition, geometry, and stiffness of the wound influence cell behaviour. In addition, we will examine the molecular signalling pathways that regulate the cellular responses to these different environments. This project has the potential to provide significant insights into how human skin cells sense and respond to extrinsic signals during the wound healing process. Moreover, this model system may be a powerful tool for future cell biology studies, drug screening, and other types of translational research.
