The development of large-scale human liver scaffolds equipped with interconnected flow channels in three-dimensional space offers a promising strategy for the advancement tissue engineering. Tissue-engineered scaffold must be blood-compatible to address demand clinical transplantable tissue. Here, we demonstrate construction 3-D macro using selective laser sintering (SLS) fabrication method. ac...
Materials and Manufacturing Techniques for Polymeric and Ceramic Scaffolds Used in Implant Dentistry
Preventive and regenerative techniques have been suggested to minimize the aesthetic functional effects caused by intraoral bone defects, enabling installation of dental implants. Among them, porous three-dimensional structures (scaffolds) composed mainly bioabsorbable ceramics, such as hydroxyapatite (HAp) β-tricalcium phosphate (β-TCP) stand out for reducing use autogenous, homogeneous, xenog...
Two groups of PLGA specimens with different geometries (notched and unnotched) were injection molded under two melting temperatures and flow rates. The mechanical properties, morphology at the fracture surface, and residual stresses were evaluated for both processing conditions. The morphology of the fractured surfaces for both specimens showed brittle and smooth fracture features for the major...
Background: Although the presence of articular cartilage progenitor cells is already known, but due to lack of blood supply, its ability to heal is poor. In past, tissue engineering approaches has been mainly focused on the collection and culture of chondrocyte cells on biodegradable scaffolds such as polyglycolic acid in vitro and their autologous transplantation. Recently, due to the difficul...
