Identification of CD2-/CD3+ T cells in fetal human tissue
نویسندگان
چکیده
From 1 to 23% of fetal human spleen or thymus cells (from the 20th to 24th week of gestation) were found to display a previously unrecognized CD2-/CD3+ phenotype. IL-2-dependent, long-term clones of CD2-/3+ T cells did not react with a panel of anti-CD2 mAbs and did not form rosettes with sheep erythrocytes. These results show that (a) significant numbers of CD2-/3+ T cells are present in fetal human spleen and/or thymus; and (b) in contrast to the widely accepted view, expression of CD2 is not a prerequisite for the expression of the CD3 molecular complex on human T cells.

Delineation of intrathymic T, NK, and dendritic cell (DC) progenitors in fetal and adult rats: demonstration of a bipotent T/DC intermediate precursor.
We previously published study results stating that the early rat fetal liver contains a high frequency of T/dendritic cells (DCs), but rarely T/NK bipotent common progenitors. Now, by using xenogenic rat/SCID mouse fetal thymic organ cultures, we extend these observations to the thymus, in which conflicting data have been published in human and mouse. On the one hand, enriched adult intrathymic...

During early fetal development, T cell precursors home from fetal yolk sac and liver to the epithelial thymic rudiment. From cells that initially colonize the thymus arise mature T cells that populate T cell zones of the peripheral lymphoid system. Whereas colonization of the thymus occurs late in the final third of gestation in the mouse, in birds and humans the thymus is colonized by hematopo...
متن کاملA novel subset of CD2-, CD3/T cell receptor alpha/beta+ human peripheral blood T cells. Phenotypic and functional characterization of interleukin 2-dependent CD2-CD3+ T cell clones
It is generally believed that CD2 (T11, sheep erythrocyte receptor) is expressed on all human T cells. In the present study we have identified and characterized a minor subset of CD2- CD3/TCR alpha/beta+ T cells in the peripheral blood of healthy individuals. CD2-CD3+ T cells were enriched in PBMC depleted of plastic-adherent macrophages, E-rosetting (i.e., CD2+) T cells and surface Ig+ B cells...

Cells from fetal liver or fetal and adult bone marrow that are membrane (m)CD3 negative and have not rearranged TCR genes but express CD3 proteins in their cytoplasm are considered to be committed T-cell progenitors. Recent findings question whether CD3 is T-cell specific because fetal natural killer (NK) cells have been shown to express cCD36 and proteins. To further examine the relationship b...
متن کاملFlow cytometric assessment of human T-cell differentiation in thymus and bone marrow.
Using multidimensional flow cytometry we have defined and quantified the human T-cell differentiation pathway, focusing on those events occurring among the most immature thymocytes and putative bone marrow (BM) T-precursors. Early thymocytes were found to express the CD34 antigen and consisted of a mean 1.2% of cells within human pediatric (n = 9) and 2.0% in fetal thymi (n = 4). All CD34+ thym...
