Decellularization is a promising new method to prepare natural matrices for tissue regeneration. Successful decellularization has been reported using various tissues including skin, tendon, and cartilage, though studies using hard tissue such as bone are lacking. In this study, we aimed to define the optimal experimental parameters to decellularize natural bone matrix using 0.5% sodium dodecyl ...

testosterone is believed to play a significant role in spermatogenesis, but its contribution to the process of spermatogenesis is not completely understood. given that extracellular matrix (ecm) facilitates differentiation of spermatogonial stem cells (sscs) during culture, the present study was conducted to elucidate whether testosterone contribute to the permissive effect of ecm on sscs diffe...

background: matrigel (extracellular matrix) can improve the growth of many cell types in vitro. objective: the aim of the present study was to determine the effect of matrigel on the development of 2-4 cells human embryos in culture. material and methods: surplus 2-4 cells human embryos, resulting from icsi, were divided into two groups (control and test). quality of embryos in both groups was ...

The limited biocompatibility of decellularized scaffolds is an ongoing challenge in tissue engineering. Here, we demonstrate the residual immunogenicity of an extensively decellularized equine carotid artery (dEAC(intens)) and identify the involved immunogenic components. EAC were submitted to an elaborated intensified decellularization protocol with SDS/sodium desoxycholate for 72 h using incr...

An approach in tissue engineering of heart valves is the use of decellularized xenogeneic matrices to avoid immune response after implantation. The decellularization process must preserve the structural components of the extracellular matrix to provide a biomechanically stable scaffold. However, it is known that in vascular lesions platelet adhesion to extracellular matrix components occurs and...

Muscle and fasciocutaneous flaps taken from autologous donor sites are currently the most utilized approach for trauma repair, accounting annually for 4.5 million procedures in the US alone. However, the donor tissue size is limited and the complications related to these surgical techniques lead to morbidities, often involving the donor sites. Alternatively, recent reports indicated that extrac...

BACKGROUND The idea of tissue decellularization to gain matrices for tissue engineering is promising. The aim of the present study is to establish a safe and reproducible protocol for solid tissue decellularization that prevents the architecture of the matrix with the inherent vascular network. METHODS The study was performed in rat kidneys which were decellularized by a SDS-based perfusion p...

Congenital vaginal anomalies and pelvic organ prolapse affect different age groups of women both have significant negative impacts on patients’ psychological well-being quality life. While surgical non-surgical treatments are available for defects, their efficacy is limited, they often result in long-term complications. Therefore, alternative treatment options urgently needed. Fortunately, tiss...
