CONTROLLING ELEMENT OF GROWING DIRECTION OF NERVE FIBER AND PRODUCTION THEREOF

摘要

PURPOSE:To stably and readily produce nerve cell in a large amount by providing the surface comprising specific (meth)acrylate resin and having many fine undulations at touching part with nerve cell. CONSTITUTION:A controlling element of growing direction of nerve cell is obtained by notching many fine undulations at touching part with the nerve cell on the surface of a molded element (molding condition: amount of light is 103-104mJ for from several sec to several min/at room temperature, of one or more photo-setting (meth)acrylate resin selected from polyethylene glycol diacrylate expressed by formula I (n is 1-6), epoxy acrylate expressed by formula II, polyethylene glycol dimethacrylate expressed by formula III (m is 1-6), bisphenol-A ethylene oxide-added dimethacrylate expressed by formula IV and tricyclodecanyl dimethylol diacrylabe expressed by formula V.
