Spermatogonia stem cells (SSCs) are a unique cell population maintaining male spermatogenesis during life, through their potential for proliferation and differentiation. The application of silicon nanoparticles (SNs) and hyaluronic acid (HA) to induce the differentiation of SSCs seems promising. Herein, we investigate the effect of SN and HA scaffolds on the progression of SSCs spermatogenesis in mice. Initially SSCs were isolated from healthy immature mice and cultured on prepared scaffolds (HA, SN, and HA/SN) in a 3D culture system...

The presence of bone morphogenetic proteins in demineralized freeze-dried bone allograft (DFDBA) are responsible for developing hard tissues in intraosseous defects. The most common mode of sterilization of bone allografts, i.e., Gamma rays, have dramatic effects on the structural and biological properties of DFDBA, leading to loss of BMPs. Ultraviolet-C radiation is a newer approach to sterilize biodegradable scaffolds, which is simple to use and ensures efficient sterilization. However, UV-C radiation has not yet been effectively studied to sterilize bone allografts...

Osteochondral allograft transplantation is a successfully proven method to repair articular cartilage defects and prevent the degenerative effects of osteoarthritis. The number of osteochondral transplantations that can be performed each year is limited by availability of donor cartilage tissue and storage time constraints. Osteochondral transplantation success has been linked to high chondrocyte viability of the donor cartilage tissue at the time of implantation. Determining optimal storage conditions for donor cartilage is essential for tissue banks to safely provide quality cartilage tissue...

Oxygen pressure plays an integral role in regulating various aspects of cellular biology. Cell metabolism, proliferation, morphology, senescence, metastasis, and angiogenesis are some instances that are affected by different tensions of oxygen. Hyperoxia or high oxygen concentration, enforces the production of reactive oxygen species (ROS) that disturbs physiological homeostasis, and consequently, in the absence of antioxidants, cells and tissues are directed to an undesired fate. On the other side, hypoxia or low oxygen concentration, impacts cell metabolism and fate strongly through inducing changes in the expression level of specific genes...

Decalcified bone matrix (DBM) is a widely used alternative material for bone transplantation. In the DBM production process, an effective particle size and the highest utilization rate of raw materials can be achieved only through multiple high-speed circulating comminution. The rat posterolateral lumbar fusion model (PLF) is the most mature small animal model for the initial evaluation of the efficacy of graft materials for bone regeneration and spinal fusion. To evaluate the differences in the in vivo osteogenic effects of DBM pulverization through 1, 5, 9, and 14 high-speed cycles, sixty athymic rats were divided into six groups: single cycling crushing (CC1), 5 cycles of crushing (CC5), 9 cycles of crushing (CC9), 13 cycles of crushing (CC13), autogenous bone graft (ABG) and negative control (NC)...
