  1. Surfaces are arranged according to their substrate. The ligands or extracellular matrix proteins (ECMPs) that are presented from those substrates and the CAMs with which they have been shown to interact (if any) are also listed. Whole ECMPs, ECMP fragments, fusion proteins, and peptides presented by amine-modified or acrylate monomer coated TCP, protein-fouling hydrogels and polymers have all demonstrated the capacity to support hPSC culture by interacting with various integrins, E-cadherins and/or heparan sulphate proteoglycans. The surfaces listed have all been reported to support hPSC culture subject to at least the minimum cell characterisation requirements outlined in Table 1. Key references have been provided for each surface.
