In Vivo Tracking of Tissue Engineered Constructs

Vasculogenic dynamics in 3D engineered tissue constructs

Implantable 3D engineered vascular tissue constructs can be formed by co-culturing endothelial and fibroblast cells on macroporous scaffolds. Here we show that these constructs can be used for studying the dynamics of neovascular formation in-vitro by a combination of live confocal imaging and an array of image processing and analysis tools, revealing multiple distinct stages of morphogenesis. ...

Functional integration of tissue-engineered bone constructs.

Fabrication of Myogenic Engineered Tissue Constructs

Despite the fact that electronic pacemakers are life-saving medical devices, their long-term performance in pediatric patients can be problematic owing to the restrictions imposed by a child's small size and their inevitable growth. Consequently, there is a genuine need for innovative therapies designed specifically for pediatric patients with cardiac rhythm disorders. We propose that a conduct...

The development of the collagen fibre network in tissue-engineered cartilage constructs in vivo. Engineered cartilage reorganises fibre network.

For long term durability of tissue-engineered cartilage implanted in vivo, the development of the collagen fibre network orientation is essential as well as the distribution of collagen, since expanded chondrocytes are known to synthesise collagen type I. Typically, these properties differ strongly between native and tissue-engineered cartilage. Nonetheless, the clinical results of a pilot stud...

Force characteristics of in vivo tissue-engineered myocardial constructs using varying cell seeding densities.

Experiments have been successfully performed culminating in functional, vascularized, three-dimensional cardiac muscle tissue. Past experience in tissue engineering has led us to the understanding that cell seeding density plays a critical role in the formation and function of both in vitro and in vivo engineered tissues. Therefore, to improve upon the mechanics of this model and to facilitate ...
