23 Jul Suspending skin tissue engineering nanofiber support and preparation method thereof
Abstract
The invention discloses a suspending skin tissue engineering nanofiber support and a preparation method of the suspending skin tissue engineering nanofiber support. The support is composed of a polylactic acid-glycolic acid copolymer nanofiber membrane and a polypropylene auxiliary strut, wherein the nanofiber membrane is prepared through an electrospinning technology, through control over process parameters and using of different receiving devices, different structures with orderly or unordered fiber arrays are obtained, and the structures are adhered together through heating and the auxiliary strut. The obtained nanofiber support can suspend on the surface of a culture solution, keep straight performance and integrity for a long time and simulate the growing environment of skin cells and is beneficial to adherency, growth, migration, multiplication and differentiation of the skin cells, and finally the tissue engineering dermis is formed. The suspending skin tissue engineering nanofiber support and the preparation method are simple in preparation technology, low in cost and easy to apply widely.
