Abstract: A material for inducing nerve regeneration in a transplantation site, or a material for recovering the function of nerve tissues in a transplantation site, the material comprising a cell structure having a thickness of at least 300 ?m that is constructed by stacking the spheroids of bone marrow-derived cells, adipose tissue-derived cells, dental pulp-derived cells, amnion-derived cells, placenta-derived cells, umbilical cord-derived cells, or umbilical cord blood-derived cells, on a needle-shaped body arranged on a substrate.

Abstract: A surface-treated metal sheet of high durability having excellent corrosion resistance, weatherability and formability, and intended mainly for use as a material for outdoor construction. It has a chemically conversion treated surface, and carries thereon an undercoat layer of an organic resin paint containing a rust-inhibitive pigment, an intermediate coating layer consisting of an adhesive layer of a modified polyolefin resin and an intermediate layer of a polyolefin resin, and formed by the simultaneous T-die extrusion of those resins, and a topcoat layer of an acrylic, urethane or polyester resin paint, or a fluororesin paint. A process for manufacturing it is also disclosed.
