Composite scaffold provides a cell delivery platform for cardiovascular repair

Composite scaffold provides a cell delivery platform for cardiovascular repair.

Control over cell engraftment, survival, and function remains critical for heart repair. We have established a tissue engineering platform for the delivery of human mesenchymal progenitor cells (MPCs) by a fully biological composite scaffold. Specifically, we developed a method for complete decellularization of human myocardium that leaves intact most elements of the extracellular matrix, as we...

A three-dimensional osteochondral composite scaffold for articular cartilage repair.

There is a recognized and urgent need for improved treatment of articular cartilage defects. Tissue engineering of cartilage using a cell-scaffold approach has demonstrated potential to offer an alternative and effective method for treating articular defects. We have developed a unique, heterogeneous, osteochondral scaffold using the TheriForm three-dimensional printing process. The material co...

Nano-gels: A versatile nano -carrier platform for drug delivery systems: A mini review

Nowadays the application of nanotechnology in different biomedical fields such as drug delivery is increasing due to its unique advantages. With this in mind, it is widely believed that nanogels as the nanometer-sized networked polymeric particles have a considerable impact on drug delivery systems as biocompatible nanocarriers due to their unique characteristics such as high loading capacity, ...

Injectable Degradable Composite Materials for Bone Repair and Drug Delivery

Autologous cartilage fragments in a composite scaffold for one stage osteochondral repair in a goat model.

We propose a culture-free approach to osteochondral repair with minced autologous cartilage fragments loaded onto a scaffold composed of a hyaluronic acid (HA)-derived membrane, platelet-rich fibrin matrix (PRFM) and fibrin glue. The aim of the study was to demonstrate in vitro the outgrowth of chondrocytes from cartilage fragments onto this scaffold and, in vivo, the formation of functional re...
