  • Support for tissue regeneration and process for producing the same
    Patent number: 7445793
    Abstract: The present invention provides a scaffold in which cells can be stably retained and grafted in a uniform distribution state in the culture, preferable proliferation ability and viability can be secured, and particularly in the case of cartilage, fixation treatment such as suture can be carried out in the transplantation into affected parts after the culture, and the mechanical strength is provided sustainable for (weighted) compression at the initial stage of transplantation. The present invention relates to a 3-dimensional porous scaffold for tissue regeneration which comprises a structure composed of vertically long-shaped pores having a pore diameter of not less than 10 ?m to not more than 500 ?m and pore length of not less than 20 ?m to not more than 1 cm being juxtaposedly arranged obtained by a production process comprising rapid freeze-drying as a key technology.
