ABSTRACT
BACKGROUND: Previous studies have demonstrated that the well combination of decellularized matrix and appropriate seeded cells could construct a tissue-engineered kidney.OBJECTIVE: To review advances in kidney tissue engineering and decellularized matrix.METHODS: The first author retrieved CNKI, Wanfang and PubMed databases for articles addressing kidney tissue engineering published from January 1996 to April 2016. The key words were decellularized matrix,extracellular matrix,tissue engineering, kidney, seeded cells in English and Chinese,respectively.RESULTS AND CONCLUSION: The decellularized matrix loses its immunogenicity due to the removal of cellular components, while it retains the important bioactive components of the extracellular matrix and the ultrastructure of the tissues and organs, making it more and more important in kidney tissue engineering. The decellularized matrix especially exerts an important role in the tissue-engineered construction of the entire kidney as driven by recently emerging all-organ acellular cell technology. Remarkable advances in kidney tissue engineering and decellularized matrix have been made in recent years, and realized the construction of a certain functional tissue-engineered kidney. However, there are still many challenges on the way to construct a completely functional tissue-engineered kidney.BACKGROUND: Previous studies have demonstrated that the well combination of decellularized matrix and appropriate seeded cells could construct a tissue-engineered kidney.OBJECTIVE: To review advances in kidney tissue engineering and decellularized matrix.METHODS: The first author retrieved CNKI, Wanfang and PubMed databases for articles addressing kidney tissue engineering published from January 1996 to April 2016.
