Plasma B cells, which move through the body releasing antibodies, are an important component of the body's fight against viral infections and other invaders. They are relatively rare, however, and increasing their ranks is ...

The process of inflammation is complex. The main role is played by immune cells migrating from the blood into the tissue to fight the inflammation. If too many of these cells are active, however, they can just as easily cause ...

Many chemotherapeutics act by damaging the DNA. Since cancer cells divide more often than most normal cells, they are more sensitive to DNA-damaging agents. One exception are oocytes. To prevent birth defects, they initiate ...

Chronic lymphocytic leukaemia (CLL) is a haematological malignancy that originates in the blood-forming cells of the bone marrow and spreads to other organs through the bloodstream. When infiltrating tissues, CLL cells come ...

The cell is the structural and functional unit of all known living organisms. It is the smallest unit of an organism that is classified as living, and is often called the building block of life. Some organisms, such as most bacteria, are unicellular (consist of a single cell). Other organisms, such as humans, are multicellular. (Humans have an estimated 100 trillion or 1014 cells; a typical cell size is 10 µm; a typical cell mass is 1 nanogram.) The largest known cell is an unfertilized ostrich egg cell.
In 1835 before the final cell theory was developed, a Czech Jan Evangelista Purkyně observed small "granules" while looking at the plant tissue through a microscope. The cell theory, first developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells. All cells come from preexisting cells. Vital functions of an organism occur within cells, and all cells contain the hereditary information necessary for regulating cell functions and for transmitting information to the next generation of cells.
The word cell comes from the Latin cellula, meaning, a small room. The descriptive name for the smallest living biological structure was chosen by Robert Hooke in a book he published in 1665 when he compared the cork cells he saw through his microscope to the small rooms monks lived in.
