Abstract: A yarn including a plurality of twists formed by twisting single fiber strand or multiple fiber strands; and fiber grooves, which are spaces formed between the twists, to provide three-dimensional growth spaces and migration paths for cells. Accordingly, a cell proliferation rate and cell viability may be enhanced by creating microenvironments suitable for migration, proliferation and differentiation of cultured cells. In addition, cell clusters having more uniform shapes may be easily implemented by forming the proliferation spaces and migration paths for the cultured cells as similar as possible to each other in each scaffold. Further, the cells cultured thereby can be cultured in a suitable shape and structure to be applied to an in vitro experimental model or transplanted into the body of an animal, and can be widely applied in various products used in a cell culture or tissue engineering field.

Abstract: Provided is a nanofiber composite membrane for guided bone regeneration, which includes: spinning a spinning solution by an electrospinning method to produce nanofibers; accumulating the nanofibers, to prepare a certain thickness of a nanofiber web; and drying and thermally calendering the nanofiber web to sterilize the nanofiber web, wherein the spinning solution contains a biocompatible plasticizer to maintain physical properties, flexibility and elasticity of the membrane, by suppressing an increase in brittleness in a sterilization treatment.

Abstract: Provided is yarn for a cell culture scaffold. The yarn for a cell culture scaffold according to an exemplary embodiment of the present invention includes slitting yarn produced by cutting a compressed nanofiber web to a predetermined width. Accordingly, by creating microenvironments suitable for migration, proliferation and differentiation of cells, cell viability may be enhanced and cells may be three-dimensionally proliferated. In addition, a scaffold according to the present invention has a mechanical strength sufficient for prevention of disruption of the scaffold which occurs during cell culture, such that cells may be stably proliferated. Further, the scaffold according to the present invention uses slitting yarn formed of the compressed nanofiber web, thereby having pores with various sizes, and therefore cell proliferation and cell viability may be enhanced by creation of an extracellular matrix-like environment.
