Title MATERIAL FOR CELL GROWTH, TISSUE REGENERATING MEMBRANE AND TISSUE REGENERATION METHOD
Abstract [Problem] To provide a material for cell growth, said material being flexible and assuring a high cell growth rate. [Solution] A scaffold material for cell growth, characterized in that the surface of a scaffold base material, which is formed of polyvinylidene chloride, has been plasma-treated by exposing to a plasmatized inert gas (for example, argon gas) atmosphere. The plasmatization can be conducted by using a magnetron sputtering device. In this case, it is preferred to employ as a target electrode a material which generates no sputtering particles in ion sputtering, for example, titanium or stainless.
