To determine whether physical topographical cues, specifically parallel microgrooves, improve the efficiency of direct genetic reprogramming of cardiac progenitor cells into functional cardiomyocytes.
Cultured cardiac progenitor cells on substrates featuring parallel microgrooves.
Used a lentivirus-mediated approach to overexpress cardiac transcription factors Myocardin, Tbx5, and Mef2c.
Assessed epigenetic modifications, sumoylation, cardiomyocyte-specific protein expression, and structural alignment, comparing effects to the histone deacetylase inhibitor valproic acid (VPA).
Microgrooved substrates increased histone H3 acetylation (AcH3) and stimulated myocardin sumoylation, mirroring the biochemical actions of valproic acid.
Topographical cues markedly augmented the expression of cardiomyocyte-specific proteins in reprogrammed cells, with no instructive response observed in cells unresponsive to VPA.
Parallel microgrooves promoted cell alignment and enhanced sarcomeric organization, mimicking native ventricular myocardium architecture.
