Three-dimensional schematic of the interstitium, a fluid-filled space supported by a network of collagen. In anatomy, the interstitium is a contiguous fluid-filled space existing between a structural barrier, such as a cell membrane or the skin, and internal structures, such as organs, including muscles and the circulatory system.
Interstitial cell refers to any cell that lies in the spaces between the functional cells of a tissue. Examples include: Interstitial cell of Cajal (ICC) Leydig cells, cells present in the male testes responsible for the production of androgen (male sex hormone) A portion of the stroma of ovary; Certain cells in the pineal gland; Renal ...
Interstitial cells of Cajal (ICC) are interstitial cells found in the gastrointestinal tract.There are different types of ICC with different functions. ICC and another type of interstitial cell, known as platelet-derived growth factor receptor alpha (PDGFRα) cells, are electrically coupled to smooth muscle cells via gap junctions, that work together as an SIP functional syncytium.

The interstitial compartment (also called "tissue space") surrounds tissue cells. It is filled with interstitial fluid, including lymph. [5] Interstitial fluid provides the immediate microenvironment that allows for movement of ions, proteins and nutrients across the cell barrier.
Interstitial fluid is essentially comparable to plasma. The interstitial fluid and plasma make up about 97% of the ECF, and a small percentage of this is lymph. Interstitial fluid is the body fluid between blood vessels and cells, [8] containing nutrients from capillaries by diffusion and holding waste products discharged by cells due to ...
[10] [11] No other interstitial cell within the testes has a nucleus or cytoplasm with these characteristics, making identification relatively easy. While any age is susceptible to a Leydig cell tumour, Leydig cell tumours are more common in people aged 5 to 10 and 30 to 35. [12] A Leydig cell tumour in a child usually causes precocious puberty ...
Interstitial fauna, small aquatic invertebrates, larger than microfauna but smaller than macrofauna Interstitial fluid , a solution that bathes and surrounds the cells of multicellular animals Interstitial deletion and duplication in genetics, see Deletion (genetics) § Types and Gene duplication
In cell biology, molecular biology and related fields, the word extracellular (or sometimes extracellular space) means "outside the cell". This space is usually taken to be outside the plasma membranes, and occupied by fluid (see extracellular matrix). The term is used in contrast to intracellular (inside the cell).
