title: The role of fibronectin in corneal wound healing explored by a physician-scientist.
abstract: For the past 30 years, I have worked as a physician-scientist in both the clinic and laboratory setting at a number of university medical schools. Encountering patients in the clinic for whom treatment was not available led me to the laboratory in an attempt to develop the appropriate treatment for future patients. The main focus of my translational research has been the role of fibronectin in corneal epithelial wound healing and the development of fibronectin eyedrops for the treatment of patients with persistent corneal epithelial defects. An extension of this research led to the development of eyedrops containing the synthetic peptide proline-histidine-serine-arginine-asparagine (PHSRN), which corresponds to the second cell-binding site of fibronectin. My clinical experience with fibronectin eyedrops also prompted me to examine the role of the sensory neurotransmitter substance P and insulin-like growth factor-1 (IGF-1) in corneal wound healing, leading to the development of eyedrops containing peptides derived from these agents (peptides FGLM-amide and SSSR, respectively). Although the path from the laboratory to the clinic in these instances has been relatively short, the time required to establish the newly identified treatment modalities in the wider community has been long. In this review, I relate the trajectory of my translational research career.
