Nanofibrous scaffold engineering using electrospinning

Scaffold plays a critical role in tissue engineering where it provides necessary structural support for the cells to accommodate and to guide their growth in the three dimensional space into a specific tissue. Therefore, engineering scaffolds favorable for cell/tissue growth is of great importance and a pre-requisite for scaffold-based tissue engineering. Electrospinning is a versatile method that has been recently adapted in engineering nano-fibrous scaffolds that mimic the structural features of biological extracellular matrix (ECM). It offers many advantages over conventional scaffold methodologies, for example, capable of producing ultra-fine fibers with high porosity, high spatial orientation, high aspect ratio, and high surface area, which are highly required for the initial cell attachment, tissue formation, and continued function. Considering these astonishing merits, this article emphasis on nano-fibrous scaffold engineering by electrospinning.
