BACKGROUND Primary cultures of isolated human adipose-derived adult stem (ADAS) cells are multipotent and differentiate in vitro along the adipocyte, chondrocyte, neuronal, osteoblast, and skeletal muscle pathways. METHODS We examined the ADAS cell yield per unit volume of liposuction tissue, and their surface protein phenotype by flow cytometry.(More)
Adipose tissue serves as a source of adipokines and cytokines with both local and systemic actions in health and disease. In this study, we examine the hypothesis that multipotent human adipose-derived stem cells (ASCs), capable of differentiating along the adipocyte, chondrocyte, and osteoblast pathways, contribute to adipose tissue-derived cytokine(More)
Inflammation removes developing and mature lymphocytes from the bone marrow (BM) and induces the appearance of developing B cells in the spleen. BM granulocyte numbers increase after lymphocyte reductions to support a reactive granulocytosis. Here, we demonstrate that inflammation, acting primarily through tumor necrosis factor alpha (TNFalpha), mobilizes(More)
BACKGROUND ALDH(br) cells express high aldehyde dehydrogenase (ALDH) activity and have progenitor cell activity in several contexts. We characterized human BM ALDH(br) cells to determine whether cell sorting based on ALDH activity isolates potentially useful populations for cell therapy. METHOD We measured the expression of ALDH and cell-surface Ag by(More)
BACKGROUND ALDH-bright (ALDH(br)) cell populations sorted from freshly collected umbilical cord blood (UCB) on the basis of their high aldehyde dehydrogenase (ALDH) activity are highly enriched for HPC. HPC with low ALDH activity (ALDH(dim)) are primarily short-term progenitors, whereas progenitors that initiate long-term cultures or establish long-term(More)
To analyze the immunoglobulin repertoire of human IgM 1 B cells and the CD5 1 and CD5 2 subsets, individual CD19 1 / IgM 1 /CD5 1 or CD5 2 B cells were sorted and non-productive as well as productive V H gene rearrangements were amplified from genomic DNA and sequenced. In both subsets, the V H 3 family was overrepresented largely as a result of(More)
BACKGROUND AIMS Delivery of cell-based therapies through the carotid artery with the use of an intra-arterial catheter could introduce aggregates and cause focal ischemia in the brain. We developed a pulse-width flow cytometry method for aggregate detection and quantification. The assay was designed to be used as a cell product release assay in a clinical(More)
