摘要： [Problem]
An object of the present invention is to provide a hollow-fiber membrane which does not require a coating treatment with a cell adhesion factor or surface modification by an electron beam or the like and which is capable of adhering and culturing cells, and a method for culturing cells using the hollow-fiber membrane.
[Solution]
A hollow-fiber membrane for cell culture which is to be used as a culture substrate for adhesive cells, in which the hollow-fiber membrane includes a hydrophobic polymer and a hydrophilic polymer, the content of the hydrophilic polymer in the whole hollow-fiber membrane is more than 0% by mass and less than 1% by mass, and the content of the hydrophilic polymer on a surface of the hollow-fiber membrane is more than 0% by mass and less than 10% by mass.

摘要： The present invention provides a modified substrate including a hydrophilic polymer wherein the soluble hydrophilic polymer ratio is 15 weight percent or less and the number of adhered human blood platelets is 10/4.3x10 mu m or less. In addition, the present invention provides a method for producing a modified substrate including a step of irradiating the substrate with radiation while the substrate is brought into contact with an aqueous solution containing a hydrophilic polymer and an antioxidant. The present invention provides a modified substrate having high hematologic compatibility wherein the hydrophilic polymer is immobilized on the surface of the substrate, and a method for producing the same.

摘要： A membrane-forming dope for non-solvent induced phase separation methods, the membrane-forming dope comprising 15 to 40 wt.% of polysulfone-based resin, 5 to 60 wt.% of polyvinylpyrrolidone, and 0.1 to 10 wt.% of polyoxyethylene sorbitan fatty acid ester, all of which are dissolved in a water-soluble organic solvent solution. A porous hollow fiber membrane is produced by spinning the membrane-forming dope by a non-solvent induced phase separation method using an aqueous liquid as a core liquid. The obtained high-performance porous hollow fiber membrane can be used as a water vapor permeable membrane used in fuel cells, because its water vapor permeability is not significantly reduced even after use in a high temperature environment such as, for example, 100 to 120°C.
