To review the latest development of amniotic fluid-derived stem cell(AFS) and to predict its future appl ication. Methods The recent articles about AFS were extensively reviewed. The origin, culture, identification, and directional differentiation as well as future appl ication of AFS were summarized and discussed. Results In 1993, AFS were thought to be exist possibly, and it was confirmed in recent years. AFS have some surface markers l ike other stem cells, and has multi-differentiated potential and extensive future appl ication in cell therapy and tissue engineering approaches. Conclusion As a new stem cell, AFS remains to be further researched.
