“…Investigators have engineered PBHV/gelatin scaffolds resembling myocardial structural properties that, following Overall ANOVA P <.05 A B C stem cell culture, can guide initial MSC and nonmyocyte cell lineages towards cardiomyogenesis as shown by expression of sarcomeric proteins and cardiac transcription factors GATA-4, Nkx2.5, and TBX-5 (67). In an interesting study by Haneef et al (136), electrostimulation of MSCseeded collagen matrices significantly increased MSC proliferation and induced expression of cardiac markers troponin I, connexin 43, sarcomeric ␣-actinin, slow myosin, fast myosin and desmin, compared with nonstimulated control matrices.…”

“…In a previous paper we demonstrated the capability of scaffolds based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate)/gelatin (PHBHV/gelatin) to induce stem cell commitment to a cardiac phenotype thanks to an optimal synergy between physico-chemical, mechanical, and structural characteristics [33]. …”

“…Most of the investigations showcased the expression of proteins typical of the cardiac tissue, and a spatial distribution or alignment of the cells inside the scaffolds. Some research groups were able to show a striation typical of myofibrils (Engelmayr et al, 2008), others the massive expression of cardiac troponins, formation of intercalated disks, and functional gap junctions (Di Felice et al, 2013; Cristallini et al, 2014). Unfortunately, the extent of differentiation shown is very far from the actual maturation required to rebuild the cardiac tissue complexity.…”
