... mRNA level increased. Analysis of myomere cross-sectional area, distribution of muscle fiber sizes and number of fibers per myomere showed that muscle hypertrophy but not hyperplasia was inhibited during fasting. Both higher igf2 mRNA level and the persistence of cell proliferation could be supporting...

... Adipogenesis Hyperplasia Hypertrophy Adipose tissue (AT) is a morphologically unique organ that accumulates lipid in response to an organism's energy status. During periods of caloric excess, AT sequesters circulating lipid which then accumulates mainly as triacylglyceride (TAG) in cytoplasmic lipid...

... that they undergo more growth via hyperplasia. These observations may be a further example of adaptive plasticity in Polypterus , allowing for greater bursts of power during terrestrial locomotion. Absolute differences in fiber size were difficult to compare between the aquatic and terrestrial groups...

.... Analysis of fibre numbers and sizes indicated that white and red myotomal muscles each develop in a different manner. In white muscle, the initial growth phase is dominated by fibre hypertrophy, while the later larval growth phase also includes significant hyperplasia. Red muscle growth is mainly due...

... by determining the number of muscle fibres (hyperplasia) and the growth of existing fibres (hypertrophy). Larvae were fed rotifers containing a high (1.4; treatment 1) or low (0.2; treatment 2) ratio of docosahexaenoic acid to eicosapentaenoic acid from day 5 after hatching. From day 17, the larvae were fed...

... hypertrophy did not alter transverse cell shape, perhaps reflecting the maintenance of short diffusion distances for small molecules as cells hypertrophy. Myocyte hypertrophy could not account entirely for the sevenfold range of ventricle masses from different-sized fish, indicating that myocyte hyperplasia...
