Abstract
A scaffolding material for culturing a stem cell, which contains a synthetic resin, and has a storage elasticity at 100° C. of 1.0×104 Pa or more and 1.0×108 Pa or less, and a ratio between the storage elasticity at 25° C. and the storage elasticity at 100° C. ((storage elasticity at 25° C.)/(storage elasticity at 100° C.)) of 1.0×101 or more and 1.0×105 or less. The scaffolding material for stem cell culture has suitable hydrophilicity and strength, high fixation of stem cells after seeding, highly efficient cell proliferation, and excellent scratch resistance.
Claims13
A container for culturing a cell, comprising a container body, and a resin film provided on at least a part of a cell culture region of the container body, wherein the container is capable of culturing a cell,
- the resin film comprising a scaffolding material for culturing a cell,
- the scaffolding material comprising a synthetic resin, and having
- a storage elasticity at 100° C. of 2.0×105 Pa to 1.0×107 Pa,
- a storage elasticity at 25° C. of 1.0×108 Pa to 1.0×1010 Pa, and
- a ratio between the storage elasticity at 25° C. and the storage elasticity at 100° C. ((storage elasticity at 25° C.)/(storage elasticity at 100° C.)) of 1.0×101 to 1.0× 105,
- wherein the synthetic resin is a polyvinyl acetal resin.
