Antigens Associated with Bursal and Thymic Reticular Epithelial Cells that chicken thymic and bursal reticular epithelial (REp) cells are able to induce in vitro the appearance of T and B lymphocyte surface markers, respectively, on embryonic precursor cells. In addition, bursa-derived factor(s) have been shown to influence B cell development (4,5). Chicken thymus RE

The Development of B Lymphocytes and Their Reactivity in Pig Fetusesaru (1). In the pig, as in other animal species, there are two distinct pathways of lymphoid cell differentiation leading to generation of B and T lymphocytes (2,3). First, lymphocytes which express markers of T-cell lineage (receptors for SRBC and binding sites for anti-pig T serum) appear in thymu

Distribution and Functional Properties of PNA+ and PNA- Cells in Central and Peripheral Lymphoid Orgition, more recent studies revealed that PNA may preferentially bind to cells acting as suppressors. PNA+ suppressor cells were detected in the fetal liver (3) and aging mouse spleen (4), as well as in the thymus of young adult animals (5). Furthermore, antigen-specific suppressors in the adult sple

Functional Studies on Subpopulations of B-Lymphocytes and Bone Marrow Cellsential stem cell in the bone marrow. The T-cell lineage has been extensively studied using the surface markers available (1,2). Although a number of studies do suggest the existence of subpopulations of B-cells, a system of functional markers analogous to the Lyt system of T-cells has not yet been d

The Proliferative Activity of Antibody Forming Cells in the Mouse Bone Marrowr DNP-Ficoll. Peak proliferative activity was found during the first few days of the response. Elimination of the proliferating cells in this period caused a profound and long-lasting suppression of the antibody formation in the marrow.

The Origin of Marginal-Zone Cells,2). Surface marker analyses (3–6) have provided strong evidence that these cells are B lymphocytes. Also marginal zone lymphocytes are absent from the spleens of rats treated with heterologous anti-μ antibody from birth (6). In rat spleens marginal-zone B cells outnumber the B lymphocytes found in
