Humanized mice are crucially important for preclinical studies. However, the development and potential function of human B cells in chimeras remain unclear. Here, we describe the study of human B cells in NOD/LtSzPrkdcscid/J (NOD/SCID) mice. In this study, we transplanted 1.0×10(5) human CD34(+) cells from umbilical cord blood (UCB) into NOD/SCID mice after pretreatment with anti-asialo GM1 antiserum and sublethal irradiation. Human CD45(+) cells were detected in the peripheral blood of the recipient mice from 6 weeks after transplantation. CD19(+) B cells accounted for the greater part of the CD45(+) cells in the human UCB-chimeric mice, but their maturational stages differed in different organs. Most of the bone marrow (BM) CD19(+) cells were immature IgM(-)IgD(-)CD24(hi)CD38(hi) B cells, whereas the mature CD5(+)IgM(+)IgD(+)CD24(int)CD38(int)CD19(+) B cells were predominantly present in the spleen and peripheral blood. Human immunoglobulin (Ig) M was detected in mouse plasma. The human B cells also secreted human interleukin-10 after stimulation with LPS in vitro. These results show that human CD34(+) cells can differentiate into human B cells in NOD/SCID mice, with development and functions that are similar to those of B cell subsets in humans. The transplantation of human CD34(+) cells into NOD/SCID mice may provide a useful tool to study the development and function of human B cells.

UI	MeSH Term	Description	Entries
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D001402	B-Lymphocytes	Lymphoid cells concerned with humoral immunity. They are short-lived cells resembling bursa-derived lymphocytes of birds in their production of immunoglobulin upon appropriate stimulation.

D014183	Transplantation, Heterologous	Transplantation between animals of different species.	Xenotransplantation,Heterograft Transplantation,Heterografting,Heterologous Transplantation,Xenograft Transplantation,Xenografting,Transplantation, Heterograft,Transplantation, Xenograft
D015703	Antigens, CD	Differentiation antigens residing on mammalian leukocytes. CD stands for cluster of differentiation, which refers to groups of monoclonal antibodies that show similar reactivity with certain subpopulations of antigens of a particular lineage or differentiation stage. The subpopulations of antigens are also known by the same CD designation.

D016513	Mice, SCID	Mice homozygous for the mutant autosomal recessive gene "scid" which is located on the centromeric end of chromosome 16. These mice lack mature, functional lymphocytes and are thus highly susceptible to lethal opportunistic infections if not chronically treated with antibiotics. The lack of B- and T-cell immunity resembles severe combined immunodeficiency (SCID) syndrome in human infants. SCID mice are useful as animal models since they are receptive to implantation of a human immune system producing SCID-human (SCID-hu) hematochimeric mice.

D016688	Mice, Inbred NOD	A strain of non-obese diabetic mice developed in Japan that has been widely studied as a model for T-cell-dependent autoimmune insulin-dependent diabetes mellitus in which insulitis is a major histopathologic feature, and in which genetic susceptibility is strongly MHC-linked.

D016753	Interleukin-10	A cytokine produced by a variety of cell types, including T-LYMPHOCYTES; MONOCYTES; DENDRITIC CELLS; and EPITHELIAL CELLS that exerts a variety of effects on immunoregulation and INFLAMMATION. Interleukin-10 combines with itself to form a homodimeric molecule that is the biologically active form of the protein.	IL-10,CSIF-10,Cytokine Synthesis Inhibitory Factor,IL10,Interleukin 10

D019172	Transplantation Conditioning	Preparative treatment of transplant recipient with various conditioning regimens including radiation, immune sera, chemotherapy, and/or immunosuppressive agents, prior to transplantation. Transplantation conditioning is very common before bone marrow transplantation.	Conditioning, Transplantation,Conditionings, Transplantation,Transplantation Conditionings
