You might have heard of hypertrophy and hyperplasia if you’ve stuck around the weight-lifting scene. There are countless debates onhypertrophy vs. hyperplasiaand whether hyperplasia happens in humans. But what’s the difference between the two, and can you induce muscle hyperplasia to grow new m...

There is also an apparent increase in the number of Leydig cells per tubule in seminomas and combined germ cell tumours with STGC. The difference, however, is not significant statistically in the group of seminomas. Hypertrophy and/or hyperplasia of Leydig cells must be considered as a ...
First, let’s define the terms hypertrophy and hyperplasia. Hypertrophy means an increase in cell size. Fat cell hypertrophy occurs when the fat cell increases in volume (by storing fatty acids as triglyceride) and skeletal muscle hypertrophy occurs when skeletal muscle increases in volume. Hyperpla...
We examined the contributions of smooth muscle cell hypertrophy and hyperplasia to this increase in mass. Cell size measurements obtained by (i) image analysis of enzyme-dispersed cells, (ii) morphometric evaluation of tissue sections, and (iii) biochemical measures of protein/cell and actin/cell ...
The enhanced synthesis paralleled the lysosome biogenesis in the papilla (see later discussion) and the hyperplasia and hypertrophy in the other renal zones (260). The increased biosynthesis is coupled to unchanged turnover rate (258, 260). During repletion, biosynthesis is reduced, turnover rate ...
However, conflicting results have shown that no association was seen between adenoid/tonsillar hyperplasia and the prevalence of Class II relationship, anterior open bite, and posterior cross bite [13,14,15]. Previous studies involved small samples and a wide age range that did not account for ...
Liver regeneration is basically a process of both hypertrophy (increase in cell size or protein content during the prereplicative stage) and hyperplasia (increase in the number of cells). However, these two events are quite separable and hyperplasia can be associated with either atrophy or hypertrop...
Increase in number of nuclei per striated muscle fiber: this can happen either through hyperplasia (new cells dividing) or myonuclear addition (new nuclei being added). Myonuclear addition refers to an increase in the number of nuclei within each cell, it’s often called “muscle cell expansion...
Angiotensin II (Ang II), an important effector of the renin–angiotensin–aldosterone system, is one of the most important factors involved in arterial remodeling.1 In addition to its role in arterial blood pressure regulation, Ang II induces vascular smooth muscle cell hyperplasia and hypertrophy ...
