  • Quantitating the CD34+ cell population can also be useful during mobilization as well as for determining the optimal timing of apheresis sessions to make sure that enough CD34+ cells have been harvested. (bdbiosciences.com)
  • The stem cells are then separated from the other blood cells by the process of apheresis, and then they are given to the patient through a catheter placed into a vein. (differencebetween.net)
  • In large patient populations, we have shown a CD56 bright natural killer (NK) population to strongly associate with a lack of cGvHD and we hypothesize that these cells function to suppress cGvHD. (haematologica.org)
  • Transcriptome analysis of a small patient cohort of CD56 bright compared to CD56 dim NK cells found the NK reg cells to also overexpress Granzyme K, IL-7R, GPR183, RANK, GM-CSFR, TCF7, and IL23A. (haematologica.org)
  • Our blood bank received 2 specimens from this patient during his admission. (medscape.com)
  • The patient was placed on mechanical ventilation with general anesthesia and paralysis to reduce peripheral oxygen demand. (medscape.com)
  • CD34-selection of stem cells reduces the risk of aGvHD, but also leads to increased infectious complications and relapse. (frontiersin.org)
  • High-risk MDS cases had a significantly higher percentage of apoptotic CD34+ cells and anti-apoptotic survivin+ cells than controls, particularly for trisomy 8 cases. (who.int)
  • CD44 percentage values in peripheral T-lymphocytes were significantly higher in patients than controls, as detected by flow cytometry. (who.int)
  • Rituximab was developed in 1986 and received FDA approval for the treatment of B cell non-Hodgkin lymphomas in 1997. (oncologynurseadvisor.com)
  • Rituximab attaches to the CD20 surface of mature B cells and destroys both normal and malignant B cells. (oncologynurseadvisor.com)
  • Pluristem Therapeutics, based in Haifa, Israel, is currently recruiting patients in the United States and Israel for its Phase 1 trial of PLX-R18 cells in this unmet need. (drugdiscoverynews.com)
  • 3 Autologous stem cell transplantation almost exclusively uses peripheral blood, while for allogeneic SCT, T-lymphocytes in the peripheral blood could pose some danger. (bdbiosciences.com)
  • Le pourcentage de CD44 dans les lymphocytes T périphériques était significativement plus élevé chez les patients que chez les témoins, comme détecté par la cytométrie en flux. (who.int)
  • Endothelial cells (ECs) also represent a component of the tumor stroma and previous data suggest an involvement in CLL pathobiology. (ovgu.de)
  • STUDY DESIGN AND METHODS Isolated CD8+ T cells from CB and PB were stimulated antigen independently with anti-CD3/CD28 stimulator beads or in an antigen-dependent manner with artificial antigen-presenting cells loaded with the HLA-A*02:01-restricted peptide of tumor-associated melanoma antigen recognized by T cells 1 (MART1). (researcher-app.com)
  • CB and PB T cells cultured in the presence of interleukin (IL)-7, IL-15, IL-12, and IL-21 were characterized for T-cell phenotype and specificity, that is, by CD107a, interferon-γ, tumor necrosis factor-α, and IL-2 expression. (researcher-app.com)
  • ALCL was recognized in 1985, when tumor cells consistently demonstrated labeling by the monoclonal antibody Ki-1, a marker later shown to recognize the CD30 antigen. (medscape.com)
