  • Patent number: 11946031
    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.
