Brief description Blood cell production in the adult mammal is normally restricted to the bone marrow. The ongoing production of blood cells is well regulated and dependent on the controlled proliferation and development of rare, multipotent precursors cells commonly termed stem cells. The blood forming stem cells exist in intimate contact with other cells and tissues that comprise the red bone marrow tissue. It is currently thought that stem cell localisation, survival and growth within the bone marrow is, in part, regulated by specific interactions between the stem cells and neighbouring cells or the biochemical products of these cells. Stem cells use specific cell surface structures or cell adhesion molecules to mediate these important interactions. This project seeks to investigate the role in blood cell production, of a specific cell surface molecule, CD164, a member of a larger family of molecules with similar structural features thought to be involved in inhibition of cell growth. The main focus of the project is to identify a ligand or binding molecule for CD164. This information will allow an investigation of the consequences of binding between CD164 and its ligand by stem cells. It is proposed that the CD164-ligand interaction is one of a number of important inhibitory interactions used to regulate proliferation of stem cells. These studies will be greatly facilitated by the generation of a mouse lacking CD164.
