Abstract (original English)
We assayed gene expressions during adipogenesis of human MSCs. Microarray assays demonstrated time-dependent increases in expression of 67 genes, including 2 genes for transcription factors that were not previously shown to be expressed during adipogenesis. INTRODUCTION Increased numbers of bone marrow adipocytes have been observed in patients with osteoporosis and aplastic anemia, but the pathological mechanisms remain unknown. Recently, microarray assays for mRNAs were used to follow adipogenic differentiation of the preadipocytic cell line, 3T3-L1, but adipogenic differentiation has not been examined in primary cells from bone marrow. Here we defined the sequence of gene expression during the adipogenesis ex vivo of human cells from bone marrow referred to as either mesenchymal stem cells or marrow stromal cells (MSCs). MSCs were plated at extremely low densities to generate single-cell derived colonies, and adipogenic differentiation of the colonies assayed by accumulation of fat vacuoles, time-lapse photomicroscopy, microarrays, and reverse transcriptase-polymerase chain reaction (RT-PCR) assays. RESULTS AND CONCLUSIONS About 30% of the colonies differentiated to adipocytes in 14 days and about 60% in 21 days. Cell proliferation was inhibited by approximately 50% in adipogenic medium. The differentiation occurred primarily at the center of the colonies, and a few adipocyte
