Abstract (original English)

Background Owing to the fact that the heart tissue is not able to repair itself. Biomaterial-based scaffolds are important cues in tissue engineering (TE) applications. Recent advances in TE have led to the development of suitable scaffold architecture for various tissue defects. Objective Given the importance of cellular therapy, it was the aim of the present study to differentiate cardio myocyte cells from human adipose-derived mesenchymal stem cells (Ad-MSCs) using suitable induction reagents (namely, 5-azacytidine and transforming growth factor beta (TGF-β)) on poly-caprolactone (PCL)/Poly aniline (PANI) Nano fibrous scaffolds prepared by electrospinning. Materials and methods For this purpose, the adipose-derived mesenchymal stem cells (Ad-MSCs) were initially isolated and characterized before cultivation on the PCL/PANI Nano fibrous scaffold to be treated for 21 days with 5-azacytidine either singly or in combination with TGF-β in medium. The scaffold's morphological and cell attachment properties were investigated using electron microscopy (SEM). Finally, the cardio myocyte differentiation of Ad-MSCs on the scaffold was studied using both quantitative Real-time PCR (qPCR) and flow-cytometry while the expression rates of the cardio myocytes' specific genes (Gata4, NKX2.5, MYH-7, and Troponin I) were also determined. Results The results of Ad-MSCs culture, MTT assay, and S
