Phenotypic Characterization of Chicken Bursal Stromal Elements
Many, if not all, of the different phases of intrabursal B-cell maturation are controlled by the stromal components. We have used an extensive panel of mAb to provide a detailed phenotypic profile of these cells. Antigenic specificities were defined for the entire surface epithelium, interfollicular surface epithelium, follicle-associated epithelium, basement membrane, basement membrane-associa...
متن کاملPhenotypic Characterization of Chicken Thymic Stromal Elements
Phenotypic profiles of the thymic stromal components provide an excellent approach to elucidating the nature of the microenvironment of this organ. To address this issue in chickens, we have produced an extensive panel of 18 mAb to the thymic stroma. These mAb have been extensively characterized with respect to their phenotypic specificities and reveal that the stromal cells are equally as comp...
متن کاملThe Ontogeny of Chicken Bursal Stromal Cells Defined by Monoclonal Antibodies
Molecules expressed on lymphoid stromal cells influence the differentiation of lymphocytes. We have examined the expression of stromal markers, identified by monoclonal antibodies, in the chicken bursa of Fabricius during ontogenic development. These results are also consistent with the hypothesis that medullary secretory cells are of mesenchymal origin, whereas the basement membrane-associated...
متن کاملOntogeny of Bursal Function in Chicken
To study the occurrence of immunocompetent cells directly responsible for antibody production, cells from yolk sac, embryonic liver, bursa of Fabricius, bone marrow, spleen, or thymus were injected together with SRBC and Brucella abortus into 4-day old cyclophosphamide-treated chicks. A second stimulation was given 4 days later, and samples taken 4 days thereafter were used for antibody titrati...
متن کاملPhenotypic characterization of endometrial stromal sarcoma of the uterus.
Endometrial stromal sarcoma (ESS) of the uterus is a rare uterine malignancy that has not been characterized in detail. To characterize the phenotype of ESS of the uterus, we extracted RNA from ESS and the stroma of normal endometrium using a tissue microdissection system and compared the expression profiles in the two tissues. After suppression subtractive hybridization and differential screen...
