1.1 Hemopoiesis Blood cells fulfill a number of important functions, including 02 and C02 transport (erythrocytes), blood clotting (platelets), specific immunity and antibody production (lymphocytes), and nonspecific defense against pathogens (monocyte,/ macrophages and granulocytes). Most blood cells have a limited life span, varying from several hours to several months. Replacement of these cells requires a daily production of approximately 2 x 1011 red and 1.5 x lOti white blood cells in an average human adult. Under changed
env!ronmental conditions (e.g., low atmospheric oxygen tension), or pathologic cond,itions, such as blood,loss, tissue damage, or infections, this production capacity may be increased at least IO-fold. The process of blood cell formation, hemopoiesis, takes
place mainly in the bone marrow (EM) in adult mammals. In'fetal hemopoiesis, liver and spleen also play an important role. There is residual hemopoiesis in the spleen of adult mice. All blood cells are derived from a small pool of pluripotent hemopoietic stem cells (HSC) IMcCulloch, 1983) IMetcalf, 1989). Most of these are kept in a quiescent state, only a small subset of HSC is actively proliferating at any moment [Becker et a!., 1965] [Moore, 19911. This population is responsible for the formation of 'daughter cells, which after
progressive cell divisions gradually lose their multipotent differentiation potential and acquire the characteristic phenotypi y and functional properties of the individual blood cell
lineages (figure 1.1). These committed progenitors undergo terminal differentiation into mature blood cells, which are released into the circulation. The mechanism by which the HSC population is maintained and develops into mature blood cells is still incompletely understood. It is possible that blood cell formation is initiated by donal expansion df activated HSC with asymmetrical cell divisions, resulting in simultaneous formation of new HSC that maintain the stem cell pool as well as committed descendants that eventually differentiate into mature blood cells [Holtzer ct ai., 19721. Alternatively, analogous to oocyte development, there might be a limited pool of
HSC, whi~h are acti~ated successively and undergo terminal differentiation into mature blood cells IRosendaal et al .. 19791. According to this theory, the daughter cells are not identical to the parent cell, indicating that 'self renewal' of HSC does not take place. In agreement with such a hypothesis, a decrease in the mean telomere length during proliferation of immature hemopoietic cells into mote differentiated precursors has bee'n observed {Vaziri ct aI., 1994] [Lansdorp, 1995]. Supported by experimental data that demonstrated limits to the self renewal capacity of the stem cell compartment after stress to the hemopoietic system [Mauch et ai., 1988], this would make depletion of the HSC compartment conceivable. However, since the daughter cells that result from the first divisions of a HSC may still be pluripotent, the HSC compartment could be effectively replenished when part of these cells return to a quiescent state.

Flow cytometric analysis of growth factor receptor expression on hemopoietic progenitors
Several models for the mechanism that regulates differentiation of HSC into the different blood cell lineages have been proposed. Commitment to differentiation may be' the result of a stochastic process [Till ct ai., 19641 [Nakahata et aI., 1982] [Tsuji and Nakahata, 1989]. According to this hypothesis, commitment to a specific lineage is determined by intrinsic properties of the cell itself and cannot be jnfluenced by external factors. Alternatively, cells may be directed to enter a particular lineage by specific microenvironmental stimuli and! Or lineage-specific hemopoietic growth factors {Curry and . Trentin, 1967] [Van Zant and Goldwasser, 1977]. According to this model, the direction HSC
differentiation wiII take is determined by the relative concentration of stimulatory and inhibitory signals. However, although in the stochastic model HSC commitment is an intrinsic property of the HSC itself, whether or not these cells will proliferate or differentiate is still dependent on the availability in the microenvironment of the appropriate OFs and other stimuli to which those cells can respond. Therefore, these models are not necessarily mutually exclusive.
