Characterization of decellularized chicken skin as a tissue engineering scaffold

Decellularization has been applied on many tissues and organs to obtain biomaterials for the applications in tissue engineering. In this study, decellularization and characterization of chicken skin was performed to provide comprehensive information and in-depth details on this material as a potential tissue scaffold. Application of Triton X-100 and sodium dodecyl sulfate (SDS) on tissues in different time intervals as two decellularization protocols were compared according to various aspects such as removal of cellular components, DNA quantification, protection of extracellular matrix (ECM), mechanical properties and cytocompatibility to find the optimum technique during preparation of decellularized scaffold. The results showed that treatment with SDS revealed better results when compared with Triton X-100 regarding to preserve tissue structure and morphology although there was no difference on efficiency of decellularization. In general, the tissues decellularized with SDS demonstrated higher level of cytocompatibility and better mechanical properties in comparison with samples treated with Triton X-100. In conclusion, this study revealed that decellularized chicken skin is a cheap, abundant, and biocompatible material that supports cell attachment, growth, and proliferation. Therefore, it could be used as a proper candidate to prepare scaffolds for the further studies on tissue engineering especially for skin tissue engineering. Decellularized chicken skin was prepared and characterized as an abundant, cheap, and biocompatible material for using it as a tissue scaffold. Tissues were treated with Triton X-100 and sodium dodecyl sulfate (SDS) in various time points and samples were compared regarding to cell removal, cell viability, mechanical properties, and preservation of extracellular matrix. 24 hours of decellularization with SDS could be the optimum method to prepare decellularized chicken skin as a scaffold for skin tissue engineering.
