Harald Homanngene (NEO) or a mutant dihydrofolate reductase gene (DHFR*). Successful transfer and expression of both genes in hematopoietic progenitor cells was demonstrated by the ability of the viruses to confer resistance to either the aminoglycoside G418 or methotrexate (MTX). It was shown that the incidence

Clemens Albrechtted and relapsed acute myelogenous leukemia (AML) patients. With few exceptions, the presence of this abnormal population of cells was found to be in good agreement with the percentage of blast cells determined morphologically. Such an abnormal population of cells was also present in 70% of AML pati

Zoltán Tarr the hypothesis that binding to extracellular matrix (ECM) governs growth factor distribution in the marrow microenvironment. Since mitogens for cells of mesodermal and neuroectodermal origin bind to heparin , heparin-like molecules (e.g. heparan sulphate) are candidate growth factor-binding stru

Ultrastructural studies of the bone marrow have revealed close physical associations of stromal cells with hemopoietic stem and progenitor cells . Continuous hemopoiesis and long term maintenance of s
