Long-term impact of maternal high-fat diet on offspring cardiac health: role of micro-RNA biogenesis

(a) Heart vs. body weight ratio of animals exposed to chow diet (CTRL) or high-fat diet (HFD). Data are expressed as mean？±？SEM; n？=？18 per group. Representative heart section image from a male rat at post-natal day 77 under control chow diet (CTRL) or HFD stained with hematoxylin–eosin staining for cell morphology analyses (scale bar？=？50？μm) (b) and Masson’s trichrome to evaluate extracellular matrix depot (scale bar？=？100？μm) (c). *P？<？0.05 and **P？<？0.01 compared to contro
