Abstract:

BACKGROUND: The electrospinning technique has been used to prepare biological scaffolds to simulate nano-fiber structure of extracellular matrix; therefore, widespread attention has been paid to the electrospinning technique in the field of regenerative medicine and tissue engineering.
OBJECTIVE: To review the articles about increasing electrospun nanofiber scaffold porosity, enlarging pore diameter, promoting cell infiltration with related technologies, in order to discover the most practical and economical technology.
METHODS: The first author retrieved CNKI database, Wanfang database and PubMed with the keywords of “cell infiltration, 3D scaffold, electrospinning” in Chinese and English, respectively. Literature retrieval period was from January 2004 to October 2014.
RESULTS AND CONCLUSION: Electrospinning technology is the most effective method for preparation of nanofiber scaffolds. Electrospinning scaffolds as tissue engineering scaffolds have become an issue of concern in the basic research year by year. However, the internal nano-scale pore of nanofiber scaffolds limits the cells to grow on the surface, so recent research has been focused on highly porous three-dimensional structure which can promote the permeable growth of cells instead of two-dimensional scaffolds. Several techniques have been used, which go from the adjustment of materials and speed of electrospinning to the applications of various kinds of complicated machines. However, the existing researches are still not mature and stable, the majority of which are applied only in vitro as cell implantation or subcutaneous implantation in small animals. The above-mentioned methods still need long-term comparative studies to confirm the feasibility in the tissue-engineered repair of organs.
