Title HIGH-STRENGTH COLLAGEN FIBER MEMBRANE AND METHOD FOR PRODUCING SAME achieved
Abstract To provide a sufficiently strong collagen fiber membrane capable of being used as a cell culture substrate, as scaffolding material for regenerative medicine (for example, regenerative material for cartilage, bone, ligament, corneal parenchyma, skin, and liver tissue), as transplant material (wound dressing material, bone grafting agent, antihemorrhagic agent, antiadhesive material, etc.), or as a drug delivery carrier, a fish-derived collagen fiber membrane is characterized by (1) having a tensile strength of 30MPa or more, (2) having a density, when measured by the gravimetric method, of 0.4g/cm3 or more, and (3) having an average membrane thickness of 1.mu.m-2mm, and a variation in membrane thickness of +-30% relative to the average membrane thickness.
