Cell support composite and method for producing cell support composite

A cell support composite comprising:

• a substrate formed of an artificial material;
• a laminin molecule or a fragment thereof which adheres to at least a part of the substrate;
• and
• a monolayer of a renal tubule epithelial cell or a renal tubule epithelial-like cell which is a cultured cell attached to the substrate via the laminin molecule or the fragment thereof, wherein the monolayer of the renal tubule epithelial cell or the renal tubule epithelial-like cell is maintained for 15 days or more,
• wherein the laminin molecule or the fragment thereof is selected from any one of
• Laminin-111 or a fragment thereof that adheres to the substrate at an amount of 0.15 μg/cm2 or more,
• Laminin-211 or a fragment thereof that adheres to the substrate at an amount of 0.52 μg/cm2 or more,
• Laminin-221 or a fragment thereof that adheres to the substrate at an amount of 0.34 μg/cm2,
• Laminin-311 or a fragment thereof that adheres to the substrate at a maximum amount after air drying of 0.5 μg/cm2 or more,
• Laminin-332 or a fragment thereof that adheres to the substrate at a maximum amount after air drying of 1.2 μg/cm2 or more,
• Laminin-421 or a fragment thereof that adheres to the substrate at an amount of 0.50 μg/cm2 or more,
• Laminin-511 or a fragment thereof that adheres to the substrate at an amount of 0.32 μg/cm2 or more,
• a variant of E8 region of Laminin-511 that adheres to the substrate at an amount of 0.15 μg/cm2 or more, and
• Laminin-521 or a fragment thereof that adheres to the substrate at an amount of 0.44 μg/cm2 or more.
