Is Muscle Hyperplasia Real? Muscle hyperplasia is real, but we lack solid evidence of whether it occurs in humans and to what degree. However, there have been several animal studies showcasing muscle hyperplasia in birds, cats, mice, and fish. Several studies involving birds have displayed stron...

during puberty, the breast tissue in females undergoes physiological hyperplasia in response to hormonal changes. Similarly, the enlargement of the uterus during pregnancy is also a form of physiological hyperplasia.
I want to expand on this a little since this gets into the potential mechanism of hyperplasia in humans. There are something calledsatellite cells in muscle. Think of these as pre-muscle cells. When they are recruited or activated, they can turn into new muscle fibers (note: there are also...

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 ...
The meaning of BENIGN PROSTATIC HYPERPLASIA is enlargement of the prostate gland caused by a benign overgrowth of chiefly glandular tissue that occurs especially in men over 50 years old and that tends to obstruct urination by constricting the urethra —
The data suggest that differences in pHi regulatory mechanisms are important in determining whether an agonist causes VSMC hypertrophy or hyperplasia. 展开 关键词: LGIC SUPERFAMILY PROTO-BINDING SITE CYS-LOOP MOTIF DOCKING MODEL ANIONIC SITE SPECIFICITY RESIDUE DOI: 10.1016/0167-4838(90)90067-P 被...
(IGF-I) is increased with higher levels of muscle activityand has been reported to stimulate hypertrophy; however, further study is necessary to understand the mechanisms. The possible role of myofiber hyperplasia (increase in myofiber number) or “fiber splitting” (longitudinal division of ...
The factors which are responsible for the final determination of the enlargement pattern (hypertrophy vs. proliferation) are unknown. The separation between hypertrophy and hyperplasia, although suggested by striking differences in cellular regulation, may be somewhat artificial, since responses leading to ...
