Myocardial hypertrophy: the distribution of cell growth within the layers of the myocardium
TA Salerno, HM Shizgal and AR Dobell
The spatial distribution of radioactively labeled microspheres was studied
in normal and in experimentally hypertrophied hearts of adult pigs. The
hearts had been "tagged" with microspheres when the pigs were young. When
the adult animal was killed, the spatial distribution of the microspheres
was identical in the normal and in the hypertrophied hearts. This
demonstrates that hypertrophic growth had occurred evenly throughout all
layers of the myocardium.
