Development and validation of cryopreserved or freeze-dried decellularized human dermis for transplantation.
For decades, dermal tissue grafts have been used in various regenerative, reconstructive, and augmentative procedures across the body. To eliminate antigenicity and immunogenic response while still preserving the individual components and collective structural integrity of the extracellular matrix (ECM), dermis can be decellularized. Acellular dermal matrix (ADM) products like such are produced to accurately serve diverse clinical purposes. The aim of the present study is to evaluate the efficacy of a novel decellularization protocol of the human dermis, which eliminates residual human genetic material without compromising the biomechanical integrity and collagenous content of the tissue. Moreover, a freeze-drying protocol was validated. The results showed that though our decellularization protocol, human dermis can be decellularized obtaining a biocompatible matrix. The procedure is completely realized in GMP aseptic condition, avoiding tissue terminal sterilization.
期刊介绍:
Cell and Tissue Banking provides a forum for disseminating information to scientists and clinicians involved in the banking and transplantation of cells and tissues. Cell and Tissue Banking is an international, peer-reviewed journal that publishes original papers in the following areas:
basic research concerning general aspects of tissue banking such as quality assurance and control of banked cells/tissues, effects of preservation and sterilisation methods on cells/tissues, biotechnology, etc.; clinical applications of banked cells/tissues; standards of practice in procurement, processing, storage and distribution of cells/tissues; ethical issues; medico-legal issues.
