Over the past few decades, the field of tissue engineering seems to have been receiving extensive attention due to its rapid growth. Nanobiotechnology has solved the existing challenge in tissue engineering using the contemporary therapies including poor vascularization of cells, low anatomical integrity of engineered cells/or tissues, immunological incompatibility with the host, and lack of functional cells. Therefore, this paper provides a systematic review of literature on the application of nanotechnology in tissue engineering.

Excerpt from the Book
Neural cells tissue engineering
The engineering of neural cells has been enhanced by nanotechnology. In neural cell engineering, there are several nanotechniques which have been employed to achieve success in engineering neural cells. Based on the available literature, it is apparent that the engineering of neural cells employ three main nanotechniques; replica moulding, electrospinning and microcontact printing. The technique of replica moulding has been adopted to enhance the maintenance of cell behavior, as well as cell shape. In one experimental study using animal model that was carried out by Bettinger et al. (2006), nanomaterials were found to enhance the culturing of neural cells. These investigators used poly (glycerol-sebacate) microfabricated silicon to investigate the cell properties and behavior of bovine aortic endothelial cells. The findings of this study indicated that replica moulding enhances the culturing of neural cells through maintaining cell behavior and shape.
In another study, the use of electrospun nanofibers was found to enhance engineering of neural cells. Xie et al. (2008) cultured neurons, astrocytes and oligodendrocytes using electrospun nanofibers, primarily polycarprolactone, and reported an improvement in cell orientation and differentiation. The results of this study were consistent with those of Yang et al. (2005) which indicated that neural stem cells exhibits increased differentiation when cultured on poly (L- lactic acid) nanofibers.
