Electrospun Nanofibers and Nanoyarn for Tissue Engineering
Electrospinning nanofiber can biomimetic Extracellular Matrix and suitable for tissue scaffolding. In our group collagen-chitosan complex nanofibers have been fabricated for skin tissue engineering, collagen-chitosan-P(LLA-CL) nanofibers tube scaffold have been fabricated for blood vessel tissue engineering, silk-P(LLA-CL) nanofibers tube scaffold have been fabricated for nerve tissue engineering.
Electrospinning fabrication technique most commonly produces relatively 2D mats and the construction 3D structure nanofibers with higher porosity is still a major challenge. In our research, two methods were used to fabricate the 3D nanofiber scaffolds. A dynamic electrospinning method were developed to fabricate the nanoyarn scaffold. The nanoyarn scaffold contained 3D aligned microstructures with larger interconnected pores and higher porosity comparing with nanofiber scaffold. The nanoyarn scaffold have been successfully used for tendon tissue regeneration of rabbit. Gelatin/PLA nanofiberous 3D scaffold was fabricated by using combined electrospinning and freeze-drying methods. Thus obtained 3D nanofiber scaffold could promote cells growth and proliferation, it also been used for cartilage tissue engineering in rabbit.
