Lineage Markers

Lineage markers (pronunciation: /ˈlɪn.i.ɪdʒ ˈmɑːr.kər/) are specific molecules or proteins that are expressed on the surface of cells and are used to identify and categorize the lineage of a cell. They are particularly important in the field of immunology and cell biology, where they are used to trace the development and differentiation of cells.

Etymology

The term "lineage markers" is derived from the English words "lineage", meaning a sequence of species each of which is considered to have evolved from its predecessor, and "marker", meaning a distinguishing trait or feature.

Related Terms

  • Hematopoietic stem cells: They are the stem cells that give rise to other blood cells. This process is called haematopoiesis.
  • Immunophenotyping: A technique used to study the protein expressed by cells. This technique is used in the identification of lineage markers.
