Molecular characterization of early human T/NK and B-lymphoid progenitor cells in umbilical cord blood.
The early stages of human lymphopoiesis are poorly characterized. Here, we compared the lymphoid potential of a novel umbilical cord blood CD34(+)CD45RA(hi)CD7(+) hematopoietic progenitor cell (HPC) population with that of CD34(+)CD45RA(hi)Lin(-)CD10(+) HPCs, previously proposed as candidate common lymphoid progenitors. Limiting-dilution and clonal analysis, fetal thymic organ cultures, and cul...
متن کاملCD26+ Cord Blood Mononuclear Cells Significantly Produce B, T, and NK Cells
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...
متن کاملHuman innate lymphoid cells.
Innate lymphoid cells (ILCs) are lymphoid cells that do not express rearranged receptors and have important effector and regulatory functions in innate immunity and tissue remodeling. ILCs are categorized into 3 groups based on their distinct patterns of cytokine production and the requirement of particular transcription factors for their development and function. Group 1 ILCs (ILC1s) produce i...
متن کاملSome recent trends in studies of human lymphoid cells: B-cells, Epstein-Barr virus, and transformation.
In this brief review we will discuss some re cent trends in work on regulatory mechanisms involved in the selective expression of differentiated markers in human B-ceIllines as weIl as the types of controls involved in the expression and function of Epstein-Barrvirus (EBV) associated markers in human cells. A problem of special interest in this connection is the relation of the expression of EB...
متن کاملImmunoglobulin formation in B lymphoid cells.
A considerable amount is known about Ig biosynthesis by mature plasma cells, which form large amounts of Ig for secretion from the cell. A brief summary is given of the formation of light (L) and heavy (H) chains by polyribosomes aligned on the endoplasmic reticulum and the rapid assembly of the chains into 7S molecules (H2L2) by disulphide bonding. There is a time-ordered secretion from the ce...
