英文摘要
Severe vocal fold (VF) mucosal injury and its associated voice impairment (dysphonia) is a debilitating and
challenging clinical problem with few treatment options, none of which are consistently effective. In patients
with such tissue impairment or loss, an engineered VF mucosa would provide a biomechanically appropriate
tissue graft for voice restoration. During our previous funding cycle, we engineered such a VF mucosa via
organotypic culture of primary vocal fold fibroblasts and epithelial cells from human donors. In a series of
preclinical experiments, the engineered mucosa recapitulated the structure and physiologic function of native
human tissue. In the current application, we propose a natural extension of our prior work by advancing
characterization of the in vitro tissue engineering process at the biological system level (Aim 1), studying
remodeling and the adaptive immune response to the engineered mucosa following in vivo heterotopic
implantation (Aim 2), and studying long-term physiologic and immunologic outcomes following in vivo
orthotopic implantation (Aim 3). These experiments will generate important preclinical safety and efficacy data.
We will combine the planned experimental work with regulatory and clinical manufacturing milestones (Aim 4),
with a final goal of holding a pre-Investigational New Drug meeting with the FDA by the end of the grant. The
tissue engineering technology outlined in this application has the potential to transform treatment of the most
recalcitrant VF tissue disorders encountered in the clinic.
