Indirect Tissue Scaffold Fabrication via Additive Manufacturing and Biomimetic Mineralization
Unlike traditional stochastic scaffold fabrication techniques, additive manufacturing (AM) can be used to create tissue-specific three-dimensional scaffolds with controlled porosity and pore geometry (meso-structure). However, due to the relatively few biocompatible materials available for …

Fabrication of tissue scaffolds using projection micro-stereolithography
… fail to capture the complexity of in vivo tissue behavior. One of the most critical features of the in vivo liver is the extensive microvasculature which allows for the delivery of nutrients and metabolites without exposing hepatocytes to de-differentiating fluidic shear stresses. A new …

Electrospun Blends of Polydioxanone and Fibrinogen for Urological Applications
The need for tissue and organ replacements cannot be satisfied by autograft and allografts alone. The purpose of this study was to investigate the feasibility of electrospinning a blend of polydioxanone and fibrinogen to produce an engineered tissue scaffold. Fiber diameter and pore size of blends …

Ultrasound-assisted Ice Nucleation, Fibroblast Migration and Oxygen Delivery in Collagen Scaffolds for Tissue Engineering
Three-dimensional, porous collagen tissue engineering scaffolds can be produced using freeze-drying. However, the stochastic nature of ice nucleation may lead to architectural variability between structures created using nominally similar preparation conditions and this can impact subsequent tissue …
