Abstract： |
The invention relates to electric filature to produce a kind of nano fiber growth gene slow-release system. This invention is compounded by biology decomposably polymer material and uses electric filature to produce a kind of nano fiber laxyly release system which contains growth gene. The method not only is operated easily and has a simple working procedure, but also can use the growth gene effectively in reducing the absent tissues. The laxly release system can emit growth gene steadily in body and avoids the lost of active of growth gene. More over, it can promote increasing of cells and tissue recovery. The production can not only be mad into the piece of velamen to transplant in the absent tissues for cure, but also be made into tissue engineering shelves to plant on cells and also be fostered out of body to increase cells for the tissue's renovation and then be transplanted in body to repair tissues. |
