Abstract
By using a bed material for cell culture having a surface composed of two domains of domain A coated with a temperature-responsive polymer and domain B composed of any one or a combination of a domain coated with a polymer having high affinity with cells, a domain coated with the temperature-responsive polymer in an amount different from the amount of the temperature-responsive polymer of domain A, and a domain coated with a polymer which responds to a temperature different from the temperature to which domain A responds, a method for the co-culture of a plurality of kinds of cells which has heretofore been difficult becomes possible.
