Abstract:
Studies on haemopoietic stem cells had led to the realisation that negative feedback inhibitors play an important role in regulating their proliferation. One such molecule was identified as MIP-1 alpha. One of a family of cytokines, originally recognised as inflammatory molecules, MIP-1 alpha is now potentially valuable as a means of manipulating and protecting haemopoietic (and possibly other) stem cells during chemotherapy. This short review briefly considers the structural classification of MIP-1 alpha and its molecular relatives and indicates some of the probable human/murine equivalent molecules outlining the evidence for the equivalence of MIP-1 alpha (murine) and LD78 (human). Sources of MIP-1 alpha/LD78 are identified as monocyte/macrophage and lymphocytic cells and their role in inflammatory responses is seen to be significant. All proliferation in haemopoietic tissue is now recognised as a major target for MIP-1 alpha action. In vitro it synergises with certain growth factors to promote progenitor cell colony formation, but effects are dependent on the maturational age of the cells promoted. With more primitive cells it is seen as inhibitory. This property is particularly valuable in vivo where MIP-1 alpha can protect stem cells against the effects of cytotoxic agents. Since it appears that leukaemic stem cell proliferation is not inhibited, MIP-1 alpha/LD78 present great potential for stem cell protection in the theatre of cytotoxic therapies.
