[Cell lines in experimental endocrinology]

Cell lines derived of endocrine tissues which are most frequently employed in experimental endocrinology are described. The cell lines represent a useful experimental model for the study of the control of synthesis and release of hormones and hormone-like agents as well as for the study of mechanisms of action of these agents in target tissues at the cellular and subcellular level. A number of the cell lines know so far are able to grow in serumfree media. These media are completely defined. This approach is promising for further progress in cellular endocrinology.
