Abstract

[PROBLEMS] To provide a tube boosting nerve regeneration with the use of collagen, which is excellent in nerve cell adhesiveness, cell growth properties and differentiation-inducing properties, as a scaffold. [MEANS FOR SOLVING PROBLEMS] A tube boosting nerve regeneration with the use of collagen as a scaffold for nerve regeneration, characterized in that the collagen employed has been purified so that the sodium chloride concentration thereof attains 2.0% by weight or less, preferably from 0.1 to 1.5% by weight on the dry basis. The collagen is purified by isoelectric precipitation at a pH value of 8 or more but less than 9.
