Proteomic analysi of decellularized porcine pancreas

The extracellular matrix is an important part of the cellular microenvironment regulating various cellular functions. Decellularized matrices present a valuable strategy for recreating the cellular niche in vitro and implementing matrix signaling in cell culture models. However, the tissue-specificity of decellularized matrices is little considered in most in vitro models. Here, we present the generation of a porcine-derived pancreas-specific decellularized extracellular matrix scaffold (d-PanMa) and show the impact of scaffold-specific cues on stem cell culture. The proteomic analysis in this work compare the proteome of porcine pancreas (PanMa), intestine (SISser) and lung (lungMa) both in its native and decellularized form. The analysis verify the enrichment of important matrisome proteins in the decellular matrices and provide a detailed map of the protein composition and abundance across the matrices.
