Rat lung decellularization using chemical detergents for lung tissue engineering.

Rat lung decellularization using chemical detergents for lung tissue engineering. Biotech Histochem. 2018 Dec 05;:1-9 Authors: Tebyanian H, Karami A, Motavallian E, Samadikuchaksaraei A, Arjmand B, Nourani MR Abstract Although pulmonary diseases account for a large number of deaths in the world, most have no treatment other than transplantation. New therapeutic methods for lung treatment include lung tissue engineering and regenerative medicine. Lung decellularization has been used to produce an appropriate scaffold for recellularization and implantation. We investigated 3-[(3-cholamidopropyl) dimethylammonio]-1-propanesulfonate (CHAPS) with sodium dodecyl sulfate (SDS) and Triton X-100 detergents for effecting rat lung decellularization. We evaluated using conventional histology, immunofluorescence staining and SEM methods for removing nuclear material while leaving intact extracellular matrix proteins and three-dimensional architecture. We investigated different concentrations of CHAPS, SDS and Triton X-100 for different periods. We found that 2 mM CHAPS + 0/1% SDS for 48 h was the best among the treatments investigated. Our method can be used to produce an appropriate scaffold for recellularization by stem cells and for investigations ex vivo and in vivo. PMID: 30516069 [PubMed - as supplied by publisher]
