Editorial Scaffolds Reinforced by Fibers or Tubes for Tissue Repair

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The final purpose of tissue engineering is to regenerate or repair defective/damaged tissues and organs. One of vital approaches is to use the various porous scaffolds to simu-late the extracellular matrix (ECM) for cellular attachment, proliferation, and differentiation. On the other hand, scaffold materials not only offer mechanical support for embedded cells, but also create a three-dimensional environment for special cells at the same time, which contributes to the repair of tissues and organs. So scaffolds have been an increasingly hot research field because its huge potential in tissue repair engineering [1–3]. Ideal scaffolds are expected to have excellent mechanical properties and biomimetic effect. In addition to porous and stereo structure, good bio-compatibility and biodegradation, and the chance to offe
