In anatomy and histology, the term wandering cell (or ameboid cell) is used to describe cells that are found in connective tissue, but are not fixed in place. This term is used occasionally and usually refers to blood leukocytes (which are not fixed and organized in solid tissue) in particular mononuclear phagocytes. Frequently, the term refers to circulating macrophages and has been used also for stationary macrophages fixed in tissues ( histiocytes), which are sometimes referred to as "resting wandering cells".
