Abstract:

BACKGROUND: Three-dimensional (3D) nanofiber scaffolds are aimed to mimic the physical and chemical signals of stem cells in vivo. 3D nanofiber scaffolds, which are capable to maintain the activity of stem cells, are promising in tissue regeneration and stem cell therapy.

OBJECTIVE: To review the synthesis methods for 3D nanofiber scaffolds, and the interactions of stem cells and 3D scaffolds as well as the current progress of 3D nanofiber scaffolds in tissue engineering.
METHODS: Web of Science was searched with key words of “tissue engineering, nanofiber scaffold, stem cell fate” in English for articles relevant to stem cell tissue engineering and 3D nanofiber scaffolds.
RESULTS AND CONCLUSION: 3D nanofiber scaffolds can mimic the physical architecture of in vivo microenvironment due to its nano-scale topology. Chemical modification of scaffolds endows chemical cues to stem cells. Therefore, 3D nanofiber scaffold can be a promising delivery vehicle of stem cells in tissue engineering. Nanofiber scaffolds can be synthesized through self-assembly, sol-gel phase separation, and electric spinning. 3D nanofiber scaffolds have been shown to improve the in vitro proliferation of hematopoietic stem cells, embryonic stem cells, mesenchymal stem cells, and neural stem cells. 3D nanofiber scaffolds with specific topology/chemical properties can induce the differentiation of stem cells into bone, cartilage, nerve, or muscle. 3D nanofiber scaffold which provides a satisfactory microenvironment for stem cell enhance the performance of stem cell therapy.
