Distinct Immunological Landscapes of HCMV-Specific T Cells in Bone Marrow and Peripheral Blood

Pathogens
Human cytomegalovirus (HCMV) establishes lifelong latency in the host, with the bone marrow (BM) CD34+ cells serving as a key reservoir. To investigate tissue-specific immune responses to CMV, we analysed paired peripheral blood mononuclear cells (PBMCs)

Flow cytometry‐based monitoring of chimeric antigen receptor (CAR) T cells: Reagent selection, assay design, and clinical utility

Cytometry Part B: Clinical Cytometry, EarlyView.
Abstract Accurate quantification of chimeric antigen receptor (CAR) T cells is essential for monitoring post‐infusion CART expansion and persistence and for real‐time clinical decision‐making. Multiparameter flow cytometry (MFC) enables rapid, live‐cell detection with absolute quantification and concurrent immunophenotypic characterization. This review

Monoclonal antibodies against human CD34 antigens do not cross-react with ovine umbilical cord blood cells

Italian Journal of Animal Science, 2010
CD34 is a cell surface glycoprotein expressed by hematopoietic progenitors and endothelial cells. It is widely used in the clinic for isolation of human hematopoietic stem cells.

Challenges and Pitfalls to Diagnosing NUTM1‐Rearranged Neoplasia of the Pancreas by Cytology and Ancillary Studies

Diagnostic Cytopathology, EarlyView.
ABSTRACT Fine‐needle aspiration cytology specimens are frequently utilized for ancillary studies to identify diagnostic and prognostic information. This case highlights diagnostic pitfalls and challenges in diagnosing NUTM1‐rearranged neoplasia on pancreatic cytology.

Small cell lung cancer can express CD34 antigen.

Anticancer research, 1998
In humans CD34 is a valid and reliable marker for hematopoletic stem and progenitor cells. In general, solid tumors, with the exception of endothelial cancers, do not express CD34. Accordingly, immunological selection of CD34+ hematopoietic stem/progenitor cells can be used to remove CD34- malignant cells in the setting of autotransplantation.

Transendocardial injection of expanded autologous CD34+ cells after myocardial infarction: Design of the EXCELLENT trial

ESC Heart Failure, Volume 12, Issue 2, Page 1455-1463, April 2025.
Abstract Aims The extent of irreversible cardiomyocyte necrosis after acute myocardial infarction (AMI) is a major determinant of residual left ventricular (LV) function and clinical outcome. Cell therapy based on CD34+ cells has emerged as an option to help repair the myocardium and to improve outcomes.

Juvenile myelomonocytic leukemia stem cells are sensitive to NK cell–mediated lysis and express targetable antigens

Blood Neoplasia
: Juvenile myelomonocytic leukemia (JMML) is a myeloproliferative neoplasm for which hematopoietic stem cell transplantation is the only curative treatment.

The use of donor-derived veto cells in hematopoietic stem cell transplantation

Frontiers in Immunology, 2012
The induction of immune tolerance by specific agents, as opposed to general immune suppression, is a most desirable goal in transplantation biology. One approach to attain this goal is afforded by the use of donor-derived cells endowed with veto activity,

Quantification of intrinsic regulatory factors refines human hematopoietic progenitor definitions and reveals early erythroid lineage priming

Cell Reports
Summary: Hematopoietic stem and progenitor cell (HSPC) transplantation is an essential therapy for hematological conditions, but finer definitions of human HSPC subsets with associated function could enable better tuning of grafts and more routine, lower-
