Cardiomyocyte culture support

摘要

Methods and reagents are described for myocardial regenerative therapy using cardiomyocytes that are cultured ex vivo to have a controlled orientation of beating. This is achieved by growing the cardiomyocytes on a culture support that is coated with a polymerizable liquid crystal which is oriented so as to be in a liquid crystal phase state prior to curing with ionizing radiation or ultraviolet rays.

主权项

1. A cardiomyocyte cell culture support system comprising:
a cardiomyocyte cell layer, and a base material coated with a continuous layer of a cured polymerizable liquid crystal having a molecular orientation on a flattened surface thereof, wherein the cardiomyocyte cells in said cell layer are attached to and aligned with the molecular orientation at the surface of said continuous layer of the cured polymerizable liquid crystal, and a water contact angle on the surface of the cured polymerizable liquid crystal layer ranges from 55° to 80°, wherein the base material has orientation ability and comprises a substrate and an oriented film on the substrate, and the cured polymerizable liquid crystal layer is formed on the oriented film.
