ABSTRACT

OBJECTIVE:

Based on the overview of progress regarding seed cells and scaffolds for skin tissue engineering, to introduce the research of three dimensional nanofiber scaffolds prepared by electrospinning technique, and its application prospect in tissue engineered skin.DATA SOURCES The databases of CNKI, Sciencedirect, and I.S.I were retrieved by the first author with key words of "tissue-engineering, skin, wound healing, seed cell, scaffold, electrospunning" in both Chinese and English from 1992 to 2009.DATA SELECTION Major accomplishments of research on skin tissue engineering published in recent years.MAIN OUTCOME

MEASURES:

Papers related to treating skin destruction using tissue engineered materials. ②Articles correlative to seed cells and scaffold materials. ③Papers regarding electrospinning technique.

RESULTS:

The preparation of artificial skins is the research direction of tissue-engineered skin, in particular, studies regarding epidermal stem cells, bone marrow mesenchymal stem cells, hair follicle stem cells, and adipose-derived stem cells are attracted more attention. As tissue engineering, it is a key problems to prepare a scaffold to meet the needs of mechanical property,physical composition and biocompatibility. Scaffold materials comprise micrometer porous scaffold and nano-fiber scaffolds. The electrospinning technique is newly developed method for preparing nano-fiber scaffolds with the advantage of fast and convenience, and the scaffolds possess greater porosity, which not only benefit for the blood circulation and oxygen exchange,but also prevent the loss of water content and protein from wound surface.

CONCLUSIONS:

Tissue engineered skin is an important ingredient of regenerative medicine, seed cells and scaffold matrixes are two core problems that call for long term investigation. With the incessant development and integration among life sciences,nanotechnology and computer technology, marvelous progress has been achieved in the perspective of comprehending the interaction between seed cells, the mutual regulation mechanism and how the architecture and properties of scaffold materials affecting the regenerative procedures.
