Hypertrophy results from an increase in cell size, whereashyperplasiastems from an increase in cell number. |
Hypertrophyis the increase in the volume of an organ or tissue due to the enlargement of its componentcells.[1]It is distinguished fromhyperplasia,in which the cells remain approximately the same size but increase in number.[2]Although hypertrophy and hyperplasia are two distinct processes, they frequently occur together, such as in the case of thehormonallyinduced proliferation and enlargement of the cells of theuterusduringpregnancy.
Eccentric hypertrophyis a type of hypertrophy where the walls and chamber of a hollow organ undergo growth in which the overall size and volume are enlarged. It is applied especially to theleft ventricleof heart.[3]Sarcomeresare added in series, as for example indilated cardiomyopathy(in contrast tohypertrophic cardiomyopathy,a type ofconcentric hypertrophy,where sarcomeres are added in parallel).
