Heatmap from proteomics analysis of dECMs, including (A) top 30 proteins that expressed differentially in dECMs [SECM (SE), DECM (DE), AECM (AE), and UECM (UE)] and (B) some unique protein clustering in terms of collagens (a), basement membrane associated proteins (b), matrix-stiffness associated proteins (c), and growth factors (d). Each type of dECM was prepared and run in duplicate (Run1 and Run2). The cell-type specificity among the 30 proteins was represented with a boxed dotted line.
