|Abstract:||Tissue engineering is an emerging area of applied research with a goal of repairing or regenerating the functions of damaged tissue that fails to heal spontaneously by using cells and synthetic functional components called scaffolds. Scaffolds made of nanofibers (herein called "nano-fibrous scaffolds") play a key role in the success of tissue engineering by providing a structural support for the cells to accommodate and guiding their growth in the three-dimensional space into a specific tissue. The orientation of these fibers is considered as one of the important features of a perfect tissue scaffold, because the fiber orientation greatly influences cell growth and related functions. Therefore, engineering scaffolds with a control over fiber orientation is essential and a prerequisite for controlling cell orientation and tissue growth. Recent advances in electrospinning have made it possible to create nano-featured scaffolds with controlled fiber orientation. Electrospinning is a straightforward, cost-effective, and versatile method, which is recently applied in engineering well-defined nano-fibrous scaffolds that hold promise in serving as a synthetic extra-cellular matrix (ECM). This article reviews the current trends in electrospinning nano-fibrous scaffolds with fiber orientation. A detailed mechanism involved in the spinning process is discussed, followed by experimental examples that show how the fiber orientation influences cellular growth behavior. This review is expected to be useful for readers to gain knowledge on the state-of-the-art of scaffold engineering by electrospinning. © Mary Ann Liebert, Inc.|
