Interstitial

Interstitial refers to the space located between the cells of a structure or part in plant or animal. It is often used in medical contexts to refer to various conditions and diseases that affect these spaces.

Overview

The term "interstitial" is derived from the Latin "interstitium" which means "a space in between". In biology and medicine, it refers to the microscopic spaces between the cells of a structure or organ. These spaces are filled with a fluid known as interstitial fluid, which provides nutrients and removes waste from the cells.

Interstitial Diseases

There are several diseases and conditions that are associated with the interstitial spaces in the body. These include:

• Interstitial lung disease: A group of disorders characterized by progressive scarring of the lung tissue between and supporting the air sacs.
• Interstitial cystitis: A chronic condition causing bladder pressure, bladder pain and sometimes pelvic pain.
• Interstitial nephritis: An inflammation of the spaces between renal tubules in the kidneys.

Interstitial Fluid

Interstitial fluid is a key component of the body's internal environment. It surrounds the cells of the body's tissues and is filled with a solution of nutrients and other substances that cells need to function. It also serves as a means of removing waste products from cells.

Interstitial Cells

Interstitial cells are cells that are located in the interstitial spaces. They have various functions depending on their location. For example, in the testes, interstitial cells produce testosterone, while in the heart, they can transform into myofibroblasts and contribute to heart disease.
