Abstract (EN): In this study, we described the modelling of the expansion/maintenance of human hematopoietic stem/ progenitor cells from adult human bone marrow. CD34(+)-enriched cell populations from bone marrow were cultured in the presence and absence of human stroma in serum-free media containing bFGF, SCF, LIF and Flt-3 ligand for several days. The cells in the culture were analysed for expansion and phenotype by flow cytometry. Although significant expansion of bone marrow cultures occurred in the presence and absence of human stroma, the results of expansion were effectively better in the presence of a stromal layer. In both situations the phenotypic analysis demonstrated a great expansion of CD 34(+)38(-) cells. The differentiative potential of bone marrow CD 34(+) cells cocultured with human stroma was primarily shifted towards the myeloid lineage with the presence of CD 15 and CD 33.
