Morphological changes and measurement of hypertrophic growth of H9c2 cardiac myocytes by PE- or ISO-induced hypertrophy. H9c2 cells were maintained in 1% serum media for 18 h and treated with PE (50 µM) or ISO (10 µM) for 48 h. The cellular hypertrophy was assayed by cell surface area measurement. Cell size was analyzed using Image Pro Plus software, and the values represent the relative area ± S.E., n = 3. *, P < 0.01.
