Abstract
The invention relates a multilayer preform obtained by electro-spinning, which preform is suitable as a scaffold for a prosthesis, which preform comprises at least one layer of microfibers and at least one layer of nanofibers, wherein the pore size of the at least one layer of microfibers is in the range of 1-300 micrometer and in that the pore size of the at least one layer of nanofibers is in the range of 1-300 micrometer. The present invention also relates to a method of producing said preform. The present invention also relates to the use of the present preform as a substrate for growing human or animal tissue thereon. The present invention furthermore relates to a method for growing human or animal tissue on a substrate, wherein the present preform is used as the substrate.
