Title:
HYDROGEL FOR CELL CULTURE, GEL KIT, METHOD FOR PRODUCING CELL CULTURE, AND METHOD FOR PRODUCING HYDROGEL FOR CELL CULTURE
Document Type and Number:
WIPO Patent Application WO/2020/004646
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a technique for controlling gene expression while reducing growth activity caused by unknown growth factors mixed in scaffold raw materials during cell culture using hydrogel as the scaffold. The present invention provides a hydrogel for cell culture: having cell growth activity, as calculated in terms of fibroblast growth factor-1 activity, of 100 pg/mL or less; an elastic modulus of 0.1-500 kPa; and a radiation-induced cross linked structure of a hydrophilic polymer.
