Retained Earnings. The accumulated profits of a corporation that are not paid out as dividends. Instead, the money is reinvested in the core business or used to pay off debt. Also called accumulated earnings or earned surplus.
In cell biology, molecular biology and related fields, the word intracellular means inside the cell. It is used in contrast to extracellular (outside the cell). The cell membrane (and, in many organisms, the cell wall) is the barrier between the two, and chemical composition of intra- and extracellular milieu (Milieu intÃ©rieur) can be radically different.
It differs from intracellular fluid (fluid within the cells) in that it generally has a high concentration of sodium and low concentration of potassium, while intracellular fluid is high in potassium and low in sodium. The fluid is often secreted by cells to provide a constant environment for cellular operations.
