(57) [Problem] To provide a material which can be used as a scaffold for regenerating a living tissue and which can induce blood vessels inside the material. SOLUTION: There is provided a fibrous material for living tissue regeneration containing a sustained-release angiogenesis-inducing substance between fibers of a fiber structure substantially consisting of fibers having a fiber diameter of 0.1 μm or more and 40 μm or less. The fiber material for guiding blood vessels of the present invention is used for applications such as a scaffold material for regenerating living tissue. In particular, by containing an angiogenesis inducer between the fibers of the fiber structure, A blood vessel can be induced inside a material serving as a scaffold for regenerating a living tissue, and by using this blood vessel-guiding fiber material, cell growth inside the material, Differentiation is promoted, and regeneration and repair of living tissues and organs can be efficiently performed. |
