Development of a tissue-engineered human oral mucosa: from the bench to the bed side.
The main objective of this publication is to make the reader aware of the complexity and steps that are necessary to make a Food and Drug Administration (FDA)-approved laboratory produced cell-based device, for use in clinical trials for reconstructive surgery. Most tissue-engineered cell-based devices are considered as 'human somatic cell therapy' and fall under the auspices of the Center of Biologic Evaluation and Research (CBER) and are considered a combination product by the FDA. We have illustrated the algorithm that is necessary to follow an Independent New Drug (IND) application by using our ex vivo produced oral mucosa equivalents (EVPOME), a tissue-engineered oral mucosa, as an example of a cell-based device that needs FDA approval prior to clinical application. By illustrating the experimental approach and presenting resulting data we attempt to explain each step that we address along the way.
