Research hotspots and application value of tissue-engineered skin
Tissue-engineered skin has a good application prospect in promoting skin tissue wound repair and scarless healing.
To review the current research progress, application and value of tissue-engineered skin in vivo and in vitro.
A computer was used to search the relevant articles in the CNKI database and PubMed database. The Chinese and English search terms were “mesenchymal stem cells; growth factors; skin; wounds; skin repair; wound healing; regenerative medicine; tissue engineering; scaffolds”. The domestic and foreign related application articles on tissue-engineered skin construction in the treatment of skin tissue injury in recent years were checked, and the research progress of mesenchymal stem cells, growth factors, scaffold materials and dressings for new treatment methods for tissue repair was also summarized. The articles irrelevant to the subject of this article were excluded, and 78 articles were finally included for the result analysis.
The construction of tissue-engineered skin involves the selection of seed cells, the application of growth factors, and the combination of multiple elements of scaffold materials. Mesenchymal stem cells are one of the important sources of tissue-engineered skin seed cells. Growth factors optimize the tissue culture environment, and scaffold materials provide appropriate mechanical support. Therefore, how to select appropriate seed cells, growth factors and scaffold materials to construct tissue-engineered skin to treat wounds and speed up repair is the focus and research direction that should be explored in the future. In addition, the development of wound materials is also a new field.
