HPB-AML-I has been considered a exceptional cell line. In spite of its establishment from the peripheral blood mononuclear cells (PBMCs) of a case with acute myeloid leukemia (AML)-M1, this cell line reportedly ha.As CD29, CD44, CD55, CD59, and CD73, but not for CD14, CD19, CD34, CD45, CD90, CD105, CD117, and HLA-DR. Karyotypic analysis showed the presence of complex abnormalities, but no reciprocal translocations typically detected in AML cases. Following the induction of differentiation toward adipocytes, chondrocytes, and osteocytes, HPB-AML-I cells showed, in conjunction with extracellular matrix formation, lipid accumulation, proteoglycan synthesis, and alkaline phosphatase expression. Mixed lymphocyte culture demonstrated that CD3+ T-cell proliferation was suppressed within the presence of HPB-AML-I cells. Conclusions: We conclude that HPB-AML-I cells seem to be distinctive neoplastic cells, which may be derived from MSCs, but are certainly not hematopoietic progenitor cells.Background Mesenchymal stem cells (MSCs) constitute a cell population, which functions self-renewal and differentiation into adipocytes, chondrocytes, and osteocytes. Human MSCs have already been isolated from several tissues and organs, like muscle, cartilage, synovium, dental pulp, bone marrow, tonsils, adipose tissues, placenta, umbilical cord, and thymus (reviewed by ). The biological roles of MSCs have been initially described by Friedenstein and colleagues in 1970s. They observed bone formation and reconstitution from the hematopoietic microenvironment in rodents with subcutaneously transplanted MSCs (reviewed by ).
