Abstract
Whole organ decellularization of complex organs, such as lungs, presents a unique opportunity for use of acellular scaffolds for ex vivo tissue engineering or for studying cell–extracellular matrix interactions ex vivo. A growing body of literature investigating decellularizing and recellularizing rodent lungs has provided important proof of concept models and rodent lungs are readily available for high throughput studies. In contrast, comparable progress in large animal and human lungs has been impeded owing to more limited availability and difficulties in handling larger tissue. While the use of smaller segments of acellular large animal or human lungs would maximize usage from a single lung, excision of small acellular segments compromises the integrity of the pleural layer, leaving the terminal ends of blood vessels and airways exposed. We have developed a novel pleural coating using non-toxic ionically crosslinked alginate or photocrosslinked methacrylated alginate which can be applied to excised acellular lung segments, permits inflation of small segments, and significantly enhances retention of cells inoculated through cannulated airways or blood vessels. Further, photocrosslinking methacrylated alginate, using eosin Y and triethanolamine at 530 nm wavelength, results in a mechanically stable pleural coating that permits effective cyclic 3-dimensional stretch, i.e., mechanical ventilation, of individual segments.
