    摘要： It is intended to provide: a method of producing nerve cells by inducing the differentiation of embryonic stem cells; a method of inducing the differentiation of embryonic stem cells into nerve cells; a medium to be used in the production method or the differentiation induction method as described above; or a method of elevating the purity of nerve cells obtained by inducing the differentiation of embryonic stem cells. Namely, a method of conveniently, selectively or economically producing nerve cells, which are applicable to the treatment of neurodegenerative diseases and the like, by inducing the differentiation of embryonic stem cells with the use of vitamin B12 or a salt thereof, and heparin, a substance having a heparin-like function or a salt thereof.

    摘要： A stent (1) having a generally tubular body formed of annular units with a plurality of cells and extendable in a radial direction from the inside thereof, wherein the annular units (4) are formed by vertically connecting the plurality of cells (6) and a plurality of the connected cells are arranged so as to surround the center axis (C1) of the stent forming the tubular body, the annular unit is arranged in the axial direction of the stent, the annular units are connected to each other at least at one position through a connection part (5), the connection part is formed of a curved part (8) having two or more arcs and a generally straight part (7) continued to the curved part, the cells are arranged by three to eight units per 10 mm in length of the stent, and the ratio of the axial length (5L) of the connection part in stent axial direction to that (6L) of the cells in stent axial direction is set to 100 to 50 to 100, whereby a high flexibility and a radiation support force can be sufficiently assured and a vasodilating capability can be increased to suppress a fore-shortening and a flare event.
