Heat map illustrating average values within each variable for each peptide functionalized substrates. Green denotes values closer to those recognized as healthy NP-specific. Each row demonstrates the best condition for each parameter, but is not compared to different items (i.e. other rows). As an example, NP cells with higher sGAG synthesis and lower COL1A1 mRNA may be produced by periods of culture upon soft substrates functionalized with P678 or AG10.
