background: umbilical cord blood (ucb) is an alternative source of hematopoietic stem cell transplantation (hsct), used in leukemia treatment. cd26+ cells, a fraction of cd34 positive cells, are a major population of ucb cells which negatively regulate the in vivo homing and engraftment of hscs. cd26 is highly expressed in various cells such as hscs, immune cells, fibroblasts, and epithelial ce...

Here we present retrieval of Peripheral Blood Mononuclear Cells by density-gradient medium based centrifugation for subsequent analysis of the leukocytes on an integrated microfluidic "Lab-on-a-Disc" cartridge. Isolation of white blood cells constitutes a critical sample preparation step for many bioassays. Centrifugo-pneumatic siphon valves are particularly suited for blood processing as they ...

Background: Type 1 diabetes (T1D) is a T cell mediated autoimmune disease targeting the insulin-producing β cells within pancreatic islets. Autoimmune diseases may develop as a consequence of altered balance between regulatory (Tregs) and autoreactive T cells. Objectives: To evaluate Treg cells frequency and suppressive function in the peripheral blood of newly diagnosed T1D patients in compari...

FRET based ratiometric switch for selective sensing of Al3+ with bio-imaging in human peripheral blood mononuclear cells (PBMCs).

Background and Objectives: The mesenchymal stem cells derived from peripheral blood (PB) have been recognized as a promising source for allogeneic cell therapy. The aim of this study was to investigate the isolation, growth and differentiation ability of peripheral blood-isolated mesenchymal stem cells. Methods: The mononuclear cells were purified from fr...

Background: Umbilical cord blood (UCB) is an alternative source of hematopoietic stem cell transplantation (HSCT), used in Leukemia treatment. CD26+ cells, a fraction of CD34 positive cells, are a major population of UCB cells which negatively regulate the in vivo homing and engraftment of HSCs. CD26 is highly expressed in various cells such as HSCs, immune cells, fibroblasts, and epithelial ce...

RNA extracted from plasma and peripheral blood mononuclear cells of patients with chronic hepatitis C were used as the template for reverse transcription followed by double in vitro enzymatic amplification with nested primers. Hepatitis C virus was detected in 14 of 15 (93.3%) plasma specimens and in 8 of 15 (53.3%) peripheral blood mononuclear cell specimens obtained from patients with chronic...
