Characterization and Expression Analysis of Mesenchymal Stem Cells from Human Bone Marrow and Adipose Tissue

Human mesenchymal stem cells (MSC), that have been reported to be present in bone marrow, adipose tissues, dermis, muscles and peripheral blood, have the potential to differentiate along different lineages including those forming bone, cartilage, fat, muscle and neuron. This differentiation potential makes MSC excellent candidates for cell-based tissue engineering. In this study, we have examined phenotypes and gene expression profile of the human adipose tissue-derived stromal cells (ATSC) in the undifferentiated states, and compared with that of bone marrow stromal cells (BMSC). ATSC were enzymatically released from adipose tissues from adult human donors and were expanded in monolayer with serial passages…
