Research Interests

The Segura laboratory research focuses on nucleic acid delivery strategies for tissue regeneration and adult stem cell differentiation applications. Non-viral gene delivery, which can be used to deliver any gene in the genome, is a safe, yet robust way to induce up-regulation of desired angiogenic signals; however, inefficient gene transfer has hindered the wide applicability of this approach. The Segura laboratory investigates novel approaches for gene delivery, which exploit the tissue-engineering matrix as a key player in the process of gene transfer. They use the principles of engineering, chemistry, and life sciences to develop biomaterials that can be used simultaneously as scaffolds to guide tissue regeneration, stem cell differentiation and guide efficient and controlled gene transfer.
