Title:
SCAFFOLDING MATERIAL FOR STEM CELL CULTURES AND STEM CELL CULTURE METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/131982
Kind Code:
A1
Abstract:
A scaffolding material for stem cell cultures, including synthetic resin, having a 100ºC storage elasticity of 1.0 × 104–1.0 × 108 Pa, and a ratio between 25ºC storage elasticity and 100ºC storage elasticity ((25ºC storage elasticity)/(100ºC storage elasticity)) of 1.0 × 101–1.0 × 105. This scaffolding material for stem cell cultures provides suitable hydrophilic properties and strength, high fixation of stem cells after seeding, highly efficient cell proliferation, and excellent scratch resistance.
