Title

EXPRESSION OF COLLAGEN 1 AND ELASTIN GENES IN MITRAL VALVULAR INTERSTITIAL CELLS WITHIN MICROFIBER REINFORCED HYDROGEL

Pages

  478-488

Abstract

 Objective: The incidence of HEART VALVE disease is increasing worldwide and the number of HEART VALVE replacements is expected to increase in the future. By mimicking the main tissue structures and properties of HEART VALVE, TISSUE ENGINEERING offers new options for the replacements. Applying an appropriate scaffold in fabricating tissue-engineered HEART VALVEs (TEHVs) is of importance since it affects the secretion of the main extracellular matrix (ECM) components, collagen 1 and ELASTIN, which are crucial in providing the proper mechanical properties of TEHVs.Materials and Methods: Using real-time polymerase chain reaction (PCR) in this experimental study, the relative expression levels ofCOLLAGEN 1 and ELASTIN were obtained for three samples of each examined sheep mitral valvular interstitial cells (MVICs) -seeded onto electrospun poly (glycerol sebacate) (PGS) -poly (e-caprolactone) (PCL) microfibrous, gelatin and hyaluronic acid based hydrogel-only and composite (PGS-PCL/hydrogel) scaffolds. This composite has been shown to create a synthetic three-dimensional (3D) microenvironment with appropriate mechanical and biological properties for MVICs.Results: Cell viability and metabolic activity were similar among all scaffold types. Our results showed that the level of relative expression of COLLAGEN 1 and ELASTIN genes was higher in the encapsulated composite scaffolds compared to PGS-PCL-only and hydrogel- only scaffolds with the difference being statistically significant (P<0.05).Conclusion: The encapsulated composite scaffolds are more conducive to ECM secretion over the PGS-PCL-only and hydrogel-only scaffolds. This composite scaffold can serve as a model scaffold for HEART VALVE TISSUE ENGINEERING.
