A native extracellular matrix material for tissue engineering applications: Characterization of pericardial fluid

In this study, the usability of PF components for the production of an ideal scaffold was investigated. For this aim, pericardial fluid (PF) was harvested from the bovine heart, then its structure and components were characterized. The results of Raman spectroscopy analysis, histological staining, and scanning electron microscopy (SEM) shows that the pericardial fluid contains collagen type I and IV, elastin, fibrin, and glycosaminoglycan (GAG), which are native extracellular matrix (ECM) components. The results demonstrated that (i) PF contains native ECM proteins and GAG such as collagen types I, III, and IV, elastin, and fibrin. (ii) The PF is highly similar to the native ECM structure. (iii) PF can significantly contribute to many tissue engineering studies as a native ECM material to increase the biocompatibility of biomaterials and to several in vitro/in vivo cell culture studies. (iv) PF containing multiple ECM molecules, can be used alone or together with hyaluronic acid, poly(ethylene glycol) (PEG), alginate, chitosan, matrigel, and gelatin methacryloyl (GelMA) materials in bioprinting systems for eliminating the disadvantages of these materials.
