What is an example of compensatory hypertrophy?

What is an example of compensatory hypertrophy?

Compensatory hyperplasia is the proliferation of cells while they maintain their differentiated structure and function. The classic example is liver regeneration (Michalopoulos and DeFrances, 1997; Trembly and Steer, 1998).

What is compensatory hypertrophy?

n. Increase in size of an organ or tissue when called upon to do additional work or to perform the work of destroyed tissue or of a paired organ.

What is compensatory hypertrophy of kidney?

Removal of one kidney elicits compensatory hypertrophy of the remaining kidney. The hypertrophy is due to enlargement of individual nephrons by an increase in epithelial cell size (Halliburton, 1969). Folic acid and growth hormone treatment also induce nephron enlargement (Nicholls et al., 1975; Norman et al., 1988).

Is compensatory hypertrophy of kidney normal?

Kidney growth and compensatory hypertrophy occurs in healthy kidneys. (A) Nephrons are produced during kidney ontogeny, and subsequently grow during juvenile/adolescent life, thus exhibiting hypertrophy with age in response to changing demands on renal use and net nephron functionality throughout the kidneys.

What is hypertrophy of kidney?

Kidney enlargement resulting from the expansion of cysts in patients with autosomal dominant polycystic kidney disease (ADPKD) is quantifiable and is associated with the decline of renal function. From: Biomarkers, Diagnostics and Precision Medicine in the Drug Industry, 2019.

Is liver regeneration hypertrophy or hyperplasia?

The dominant processes leading to regeneration of the liver following removal of tissue (partial hepatectomy) are compensatory hypertrophy (enlargement of hepatocytes) followed by hyperplasia (proliferation of hepatocytes).

What exhibits compensatory hypertrophy?

1. hypertrophic cardiomyopathy. 2. the term is sometimes limited to cases of hypertrophic cardiomyopathy in which the hypertrophy is localized to the interventricular septum.

What causes compensatory hypertrophy?

The growth can be a result of increased cell size (compensatory hypertrophy) or an increase in cell division (compensatory hyperplasia) or both. For instance, if one kidney is surgically removed, the cells of other kidney divide at an increased rate.

What is true hypertrophy?

Hypertrophy caused by an increase in the size of all the different tissues composing a part.

Why there is compensatory hypertrophy in DNS?

Introduction: The compensatory hypertrophy of the inferior turbinate in patients with septal deviation to one of the nostrils is considered to protect the airways from the excess of air that could enter through the nostril and its potential negative effects such as dryness, alteration of air filtration, mucociliary …

What is compensatory regeneration?

Compensatory growth is a type of regenerative growth that can take place in a number of human organs after the organs are either damaged, removed, or cease to function. Additionally, increased functional demand can also stimulate this growth in tissues and organs.

When does compensatory hypertrophy occur in the body?

Like regeneration, this phenomenon—known as compensatory hypertrophy—can take place only if some portion of the original structure is left to react to the loss. If three-quarters of the human liver is removed, for example, the remaining fraction enlarges to a mass equivalent to the original organ.

What does the compensatory response do to the body?

In effect, compensatory responses represent the body’s way of fighting the invasion of drugs. Therefore, the compensatory responses, try to keep the peace in a person’s body, or the compensatory reponses try to maintain a homostatis balance in the body.

What is the definition of compensatory hyperplasia?

Compensatory hyperplasia is the proliferation of cells while they maintain their differentiated structure and function.

Can a heart regenerate with compensatory hyperplasia?

Like other systems regenerating by compensatory hyperplasia (liver, pancreas) the heart harbors stem cells (Anversa et al., 2007; Wu et al., 2008, for review).
